Although I believe that synthetic is better, I read somewhere that an older engine that never saw synthetic before should be kept on dino for the following reason: the synthetic is thinner, and may find leaks that the dino wouldn't. Any thoughts on that?

Synth is NOT thinner. 10w-40 is 10w-40.
Any leaks that it "causes" already existed, but were plugged. The higher detergent content in most synth oils will wash away the plug.
One of the forum favorites is Rotella. If you prefer dino, get the white jug of 15w-40. If you want synth, get the bule jug of 5w-40.
Pass the popcorn, this might get interesting.

Ha, I was chided for asking an oil question last year....a commonly asked and well documented subject. I switched to synthetic with no problems.....sigpic

I don't like dino oil.
I prefer my oil to come from trilobites for two valve per cylinder engines. For the four valve engines, woolly mammoth oil seems to work best.sigpic

If you like tar sands oil, you might also appreciate some Engine Scrub from KaleCo Auto.Originally posted by bccap View Post

Synthetic VS Dino Oil... An old debate in the motorcycle world in my opinion...
Here is what I think I know...
Synthetic has better 'Flow' properties and will present the leaks that you didn't know you had.
Synthetic also has better shear properties meaning that it breaks down much less slowly so you can go further on the oil and still retain the lubricating properties.
For Synthetic I prefer Rotella T6 (blue jug)
For Dino oil (I like to use this in my older bikes 30+ years) I buy DELO 400 (Diesel Engine Lubricating Oil 400) .
At Wal*mart you can get a gallon for about $13. It is a great motorcycle oil and fabulous for wet clutches as it has nearly zero additives that are friction modifiers (bad news for wet clutches)

That's what I'm concerned about. A 32-year-old engine that already has enough wet spots.1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

As Steve pointed out in the 2nd post of this thread, oils with the same viscosity (10w-40, etc.) have identical "flow" and cannot be more likely to get through a passage.Dogma

" ...Synthetic base oils give enhanced performance because they are manufactured using advanced chemical processes, so their molecular structure and hence, their properties, can be closely controlled. For example, fully synthetic oils like Shell Helix Ultra are designed to flow more easily at start-up temperatures.."

Flip a coin
I use synthetic because valvetrains and bearings are pricier than the value of the oil used.
I especially like the flow rate when its -30 C in January.Comment
