high mileage oil

[Guest]

I know there are a million oil threads but other than a fork seal thread, non touched on High mileage oil.


It appears that Mobil one by me only comes in high mileage form now 10W-40.

I was wondering if it would swell the clutch linings at all and if anyone has had any bad results with using high mileage oil on a bike.

I think you would be fine. The "High Milage" business sounds like marketing gobbly gook to me. You may as well compare the price to Mobil 1 motorcycle oil while you are at it. I don't think it will make much if any difference but if the price is the same it seems like an obvious choice.

As long as it's not marked "Energy Conserving" on the back, you should be OK as far as the clutch goes. Energy conserving oils can cause your clutch to slip. Motorcycle specific oil is better for your engine and clutch though - Castrol Act-evo and Mobil 1 motorcycle oil are both great choices.

Actually there is something to the "high mileage" thing. It has additives designed to swell seals. I'd avoid it.

Oh man, I hadn't thought of that! I was going to switch over to it at the next oil change too! Nuts... so much for a $20 mobile one oil change. Time to google that problem....

I found Mobil 1 15W-50 synthetic at CostCo last week for $30 for a box of 6 quarts. It has the red cap and is not marked high mileage or energy conserving.

I loved this stuff -- it's a superb motorcycle oil -- but I thought they stopped making it a couple of years ago.

Have I stumbled across a dusty pallet of leftovers (and therefore I need to go back and stock up pronto), or have they started making it again?

I have put the high mileage to the test and it does help slow leaks.

My biggest fear is that whatever the special agent is that swells fiberous materials will negatively affect the clutch.

Perhaps I will stick with either Castrol GTX 10-40 as my pop has used all of his bikes life, or Rotella 15W-40 blue or white jug.

I've had great success with Castrol so far, so perhaps I will stick with that.

I just wanted to raise awareness about the possible high mileage oil swelling/ruing clutch fibers. Not saying that I proven it has, I was looking for someone who has tried it to disprove my theory.
