What brand of oil do you use?  By  danno (Read 3,774 times)

Just wondering why not?

And my answer to danno is, "Whatever the bike mech put in there." edit--I do know it's not cheap whatever grade. I don't remember now, but I did actually recognize the brand from being mentioned here.

I don't suggest it because in researching it I found that half the pro's were for it and half against. There were quite a few people that damaged motors due to mixing mineral and synthetic. I suppose you can drain off the synthetic and go back to mineral, but I prefer the fact that synthetic is a superior oil, so I won't go back. Some expensive vehicle brands insist that only synthetic be used. Some engine rebuilders hate doing motors that have had additives or synthetic in as they are harder to bore and hone due to the slippery lubes.

howdy, i'll answer because you asked what the forum users do and why. i personally use synthetic when i have the engine broken in and have found in fact that -if i remember correctly- sym, kymco and piaggio scooters that i have owned reccomend synthetics. i have used it in all my vehicles since 1975. the specific brand i use mostly is mobil 1.

lotsa miles and smiles to ya

You don't need to worry about running synthetic effecting a wet clutch on most of these scooters. Most of our bikes (if not all) use dry clutches.

I use mineral oil in my gy6 motors, and synthetic in my Aprilia and Goldwing. On the gy-6 motors, the oil isn't in long enough to really take advantage of the synthetic due to the lack of oil filter. Just keep it clean it and it's all good (1/2 a quart of oil every 1000 miles is nothing). The Aprilia has an oil filter and Aprilia recommends synthetic and they of course, know way more about engineering and metallurgy then I do. It currently has Castrol 4t synthetic in it, but will get changed to Rotella next change. The Gold wing gets Rotella synthetic blend(recommended by the forums, and the trans works better using it)

So then you are telling me that you know everything and that all the cases of where motors have been damaged are lies?
I mentioned above that there are many different theories, from pro's to the vocal ignorant, but I am not prepared to risk it. On most if not all modern models, BMW & Mercedes insist on synthetic, and will void a warranty if other oil is used. No offence intended, but I will rather follow their advice.

I've been using 10w30 Castrol dino oil this time around. It's what I put in my first engine, and that engine lasted the longest--- although it was a stock engine without a BBK, and I got around 15,000 on the crank before it went out. It wasn't always Castrol though. I also used 5w30 Honda brand a few times, too.

I know most people on here seem to use 10w40 dino or syn, and that's what I used on my other 3 or so engines(plus rebuilds), but I'm taking my own route this time around.

I've also been changing my oil very frequently. Obviously I changed it before I even started the engine at 0 miles(for the engine not my odometer--it was around 40,160). Then again at 40,360 (200 miles later), 40,673 (313 miles later), 41,211 (538 miles later), 41,817 (606 miles later), 42,508 (691 miles later).

I also ride my scooter at full throttle constantly, probably 100 miles a week on a good week--- and that's true miles, not chinometers like the numbers in my post above this paragraph. I beat it up, for a little 72cc engine.
