    Oil info from the "poll" section.

    Due to my amazement, many of you are STILL using auto oils in your precious bikes. Don't do that anymore OK?

    Below is my post I put in the "Polls" section. As an Ex. Suzuki employee I felt the information is important enough that I thought I'd post it again here.

    This is the very laymans version of why to use M/C specific oils........

    I've sat in many (too many) hours of meetings with different oil formulators some huge (like Shell), others small (like Motul, Amsoil and Spectro). While I absorbed as much of the scientific details as possible, unless your an oil engineer, which I'm not, the best you can do is understand theory. So here is the basic theory,

    In the old days, cars and motorcycles could share their oils hapily. First came catalytic converters. Then came fuel economy regulations and all of a sudden cars had certain economy numbers to meet and sulfur was deemed a catalyst destroyer ! Sulfer is a WONDERFUL lubricant and gear cushion in oils. So to compensate for the loss of sulfur and several key oil ingredients, Moly (a VERY slippery substance) and several other polymers were added. Now as a AUTO oil, these blends work GREAT! However, they were causing clutch slippage and other internal issues in motorcycle engines and gear cases. That was the beginning of M/C Specific oils.

    The latest discussions were as of late, that the EPA and CAFE have stepped up their requirements for auto's to the point that we will in the very near future be seeing vehicle specific motor oils. Your new 2008 Honda Civic will HAVE to use Honda's (or whomever also meets that spec) specific oil.

    Back to motorcycles.....

    Motorcycles have several unique issues that are rarely thought of when Joe Schmo walks into his local Wal-Mart and buys his 99 cent quart of oil. They are this:

    1: Wet Clutch- while your clutch may not be slipping now (especially on the lower Torque GS motors) The additives in Auto oil ARE affecting it. Some can get away with it...some cant. We had GSXR1000's with slipping clutches within 100 miles of normal usage after the owner put in Auto oil at his 1'st oil change...too save a few bucks....(cost him hundreds in the long run).

    2: High RPM. Find me a auto engine that redlines above 10K and doesn't DEMAND a special oil. New 600's are reving to 17,500rpm STOCK!!!

    3: Transmissions sharing oil with the motor. LOTS of sheering action here, synthetic oil is good to help prevent molecular chain sheering (viscosity break down). Cars use a specific tranny fluid. You wouldn't pour GL5 in your car engine now would you...??

    4: and the least thought about.....Motorcycles are not typically not used everyday and tend to sit around accumulating moisture inside the motor. M/C oils have additives that allow the oil to coat the metal parts for longer periods of time while sitting (marine engines use ALOT of the additive because rust is such an issue)

    So now that the API isn't catering to motorcycles anymore the Japanese motorcycle manufacturers joined up and formed JASO to discuss motorcycle specific lubrication issues. MA is their best rating (almost always a synthetic), MB is 2nd best (usually a dino oil). USE ONLY MA OR MB RATED JASO OILS FROM NOW ON.

    Synthetics are better than Dino oils (we all know that right??) Use the best oil you can afford.

    Suzuki oil is very good, Mobil 1 M/C oil is very good, their are MANY more oils that are very good...ELF, Motul, Redline, Harley Synthetic...etc Look for the JASO lable.

    The testing Suzuki used to approve it's own oils is so severe, you will NEVER be able to duplicate it on the road or on the track, I don't care who you are.

    Use M/C specific oils and quit being cheap.....the more they sell, the lower the cost will go. Like Plasma TV's !

    I hope this helps.......and go easy on the Crisco. ;-)

    What about the problems with using synthetic oil and clutch slippage?

      Just some "other' thoughts on oils...

      It also, unfortunately, when mixed with moisture from the air, creates Sulphuric acid, which does wonders for corrosion.

      Most of these oils are solely developed to ensure CAFE requirements are met for Fuel efficiency and pollution control in each vehicle. this is why most newer vehicles are spec'd' for 5w-20 oils in the USA and identical engines used outside the USA are spec'd' for heavier oils.

      This is an ongoing debate. some effect the plates, others never have a problem

      and what are those engines specifying for oils? 10w-40 (insert Manufacturer name here)?

      Some Ford and other Transmissions specified the use of standard OTC motor oil. The shearing will take place regardless of whether the oils are M/C specific or auto.

      another reason to use low-sulpher oils. ANY oil with Esther's in the mix will 'cling' to engine parts.

      JASO is another form of the society Of Automotive Engineers (SAE) Merely standards developed by manufacturers and Refiners.

      Mobile 1 M/C oil is VERY close in additive formulation to the supersyn formula used in auto engines. Up until very recently, AMSOIL M/C oil was IDENTICAL to the 10w-40 Auto oils with one exception: a picture of a motorcycle on the cover.

      I hate to say this, but this is a debate where you will get pro's and con's on both sides, and never a real agreement either way. They will use what has been successful to them in their bikes and probably won't change.

        I agree with you on your last sentance Tom but my point from the very begining was to explain in my professional opinion, gained from experience (25 years in the industry), severe duty scientific testing and proven fact why one should use motorcycle specific oils. Ignorance is bliss to many and if that works for someone than keep using whatever you use. Any oil is better than no oil. I don't sell oil, bikes or parts. I could care less what Wal-Mart brand you or anyone else uses.

        I suppose I could also teach safe sex and be confronted with equal ignorant reasons why you shouldn't wear a condom, that's up to the individual person too. I was simply trying to arm fellow riders with knowledge.

        Everyone should ask themselves this: Do you buy cheap IRC tires? They are round and black and roll well. Do you buy generic canned foods? Do you buy Generic toilet paper? You can do that and save money but I doubt you do. While like auto oil they all do as advertised, some are just better than others. It's a personal preference I guess.

        Robin, Synthetic M/C oils create no clutch problems. Nor are there any break-in issues with synthetics. They are actually "factory-fill" on many vehicles now.

        In everything mechanical I own is synthetic oils and I've never experienced any problems. Hell I just noticed my 4-stroke Ryobi weed eater/blower/edger/tiller/vac combo is now going on 6 years old and runs perfect with only Mobil 1 in it since new (3 oil changes).....and I use it at least 1 hour every weekend.

        Hope this helps,
        Kelzer

          The Kelzer, I agree with the information that 83'GK has posted. Take a look at the post at Motorcycle Motor Oil and click on the link with the same name. The article was written by a person with expert oil knowledge and a highly qualified oil industry background.

          I can also point you to other articles and research that all indicate that it is unnecessary to use "motorcycle oil".

            There have been issues with certain oils causing 'clutch slippage' due to certain ingredients in the additives, however, each bike is different, as are the various oils on the market. I have used several in mine, Mobil one, pennzoil, castrol GTX and Syntec, and currently run Rotella 15w-40 HDD. I have the origianl clutch in my 65000+ mile bike, with no issues ever excpet for a broken clutch cable. There have been several tests on various M/C oils, the two worst that repeatedly come to mind (for shearing, lack of additives per UOA ) are Golden Spectro and Honda factory fill. Sure you may save a $100 clutch, but toast a $1000 engine over the long haul.

              Boondocks,

              You're right!! DAMN you caught me, I'm full of crap and don't know my butt from a hole in the ground....but the guy that wrote that OTHER article must be treated as though his word is gospel because he agreed with your limited point of view. Sounds like a wise decision.

              FACT - Current auto oil doesn't work as good as current motorcycle oils in motorcycles. That is why we developed a motorcycle specific oil. 'Nuff said.

              I've said all I can on the subject.

              It's your bike.

                Actually yes I do and they work quite well. In addition to being the only company to make the correct size rear for my ride I find they handle well, last 5000 miles and work good in the rain. The Inohe Rubber Corporation is not a bad manufacturer.

                  Must have caught us both! couldnt be because the motor oil companies saw the opportunity to market some crap so we would spend 3x as much on often mediocre oils with a motorcycle on the bottle.....

                    However it's spelled, (sulfur/sulfer) sulphur is a contaminant in gasoline, diesel fuel, and motor oil. It may have some benefits in gear oil, but not motor oil. The sulphur that contaminates catalytic converters comes from the sulphur in low-grade gasoline, not motor oil. The lowest grades of motor oils have the highest sulphur concentrations, and the better grades refine the oil to the lowest sulphur levels possible. Only Group IV and V synthetics have no sulphur. You won't find sulphur spec'ed in any motor oil standard except as a maximum amount allowed, as it is an undesirable component. Crude oil with a high sulphur content is called "sour crude", i.e., undesirable. As 83'GK has mentioned, sulphur, air and water combine to produce sulphuric acid, which is the last thing you want in your engine. Additives in oil are specifically formulated to counteract the nasty tendencies of sulphur.

                    Automotive oils in the viscositiy range recommended for motorcycles, are not "Energy Conserving" formulations, and do not contain extra moly as the lower viscosity oil marked "Energy Conserving" may. Therefore, the "moly clutch slippage" argument regarding automotive oils is moot. In fact if you click on the link below for "Part 2: Laboratory and Dyno analysis", you will find, ironically enough that the average moly content in the "motorcycle oils" was higher than in the automotive oils.

                    Not a fact. It is a fact that motorcycle oil development has been stopped at the API SH stage, which means that it is of lower quality than the latest API SL or SM grades. With no relabeling or product improvements required, this static development allows the packagers of motorcycle oil to maximize their profits.

                    Motorcyle oils are an accessory item that will work OK in motorcycles at an inflated price. They were developed primarily to make money and confound the gullible.

                      in the Ford motor company line most manual transmissions now use a.t.f (gotta keep up the c.a.f.e. standards you know) not a gl5. and yes older ford transmissions and transfer cases used... MOTOR OIL.

                        Shear Luck? I Don't Think So.

                        In the service manual for my 1989 Honda Civic SI, the specifications for the 5 speed manual transmission call for 1.9 quarts of 10W-30 or 10W-40 motor oil only, to be changed every 30,000 miles. The transmission is still fine at 230,000 miles.

                          I'll chime in with another car that takes motor oil in the tranny. My MGB takes 20W50 in the transmission, same as the engine.

                            The Kelzer,

                            You would serve your argument much better my making references to testing and result from INDEPENDENT experts and organizations. That would be testing done by people who have no financial interest in the outcome of the tests. That would not be a study by testers in any way reliant for finances or future business upon entities involved in manufacturing and/or marketing motorcycle specific oil.

                            I would be quite interested in seeing such a study as I have yet to come across one in the half dozen motorcyle periodicals I have been reading every month for the last 30+ years; in fact, the opposite has been the case. In all such studies I have read the conclusion has been that while synthetic tends to offer advantages over dino, there is no meaningful distinction between automotive and motorcycle specific oils. In fact I have seen published results that that have some brands of motorcycle specific oil faring worse than most automobile oil in viscosity breakdown.

                            I have 130,000 miles on my 850 which I bought new in December of 1979. I have never used a drop of motorcycle specific oil in the 26 years. Most of those miles the bike held Mobil 1 automobile oil. I must admit that at times there was an excessive gap between oil changes and that at times I let it get dangerously low on oil. The bike was running good at 100,000 on the original set of rings when I had a rebuild done more or less as a reward to my trusty machine and to prepare it for the next 20 years and 100,000 miles.

                            Don't take personal offense at having your opinon questioned. GSR has a little sharper bunch than most motorcycle websites. You need to be prepared to defend your thesis in an objective and logical manner including links to documentation. If you are willing and able to do that you will receive the respect of the other members. Otherwise you would probably do best to avoid challenging statements and for godsakes stay out of the political threads.
                            Believe in truth. To abandon fact is to abandon freedom.

                            Nature bats last.

                              So let's establish some street creds for you 'The Kelzer', just what did you do for Suzuki?

                              I worked for General Electric as a temp laborer in their glass lightbulb plant when I was between gigs many years ago. I don't tell anybody how to build jet engines, or what lubricant to use in them.
