Engine oil VALVOLINE or MOTUL

I've been running Valvoline for the moly content. Not burning oil yet, fingers crossed.

I'm using motul x clean 5w40 for the last 15 years on my m54b22 and it s perfect. I tried also ravenol, liquimolly but motul was the best.

I'm on my first run of Motul 7100. It's ester based and has truly made a noticable difference in operation. It's made for motorcycles and their higher revs in mind, with the esters actually bonding to metal- not just a strong film. The drawback here is that from this bonding, the oil can be a bit stronger to burn off, but I didn't feel, like mentioned in another comment, that the internal temps on an RE can't burn that off. Just need to be sure to drive it like it's supposed to be, with high rpms. Instantly on first change I could notice quieter and smoother operation. I'm really not concerned about it not burning high enough, but as always, the most important thing is staying on top of oil changes routinely and timely. That is what truly kills most of these motors. In fact, I can't say I've really ever heard anyone lose a motor and say it was because "this" oil was used.. Unless it was something or some grade that shouldn't have been used at all in the first place.

I'd recommend using some Valvoline for your oil changes from now on, particularly their Restore & Protect line. It shut those noisy lifters up in 2 oil changes on my old '09 Avalon, and good lord did it flush out a bunch of gunk I didn't know was in there. I got a few MPG's more after it was said and done, too, and she ran happy.

Use good oil, always helps. Try valvoline restore and Protect. Quieted my engine down a little

MOTUL 8100 ECO-LITE 5W-30: Don't let the name fool you, it's not actually that great for fuel economy compared to some others with a lower KV. With a TBN of 8.5, VI of 166 and KV of 11.4, this is one of the best 5W-30 oils you can get. This is leaning more towards a higher performance oil rather than focusing on fuel econ. The high TBN means you can get away with longer OCIs as well. I am personally using this in our 1.8L Corolla at home and the car runs smoothly and quietly and still gives us a good fuel average (for our use case), so I can't complain.

Motul 5w-40 in my ej255 pretty much since the whole life of the engine since its engine 35k ago. ... went back to Motul right after.

I'm one of the Motul 5w40 users. I use it because I live in west Texas where we will have weeks in a row over 100⁰F. I've also modified my car and take it to track days. This was the oil recommended by my tuner so that's what I use.

I use Motul 8100 5w-30. But I've heard the Ravenol is good, I think it's what one of the 86 racing series runs.

I also tried Ravenol's MT fluid, and I'm thinking I'm going back to it after the RedLine.

I won't recommend Motul for Gixxer 250

10w-50 7100 makes the engine run a little hot and refinement goes for a toss (Personal Experience) even Gixxer riders group agreed on this one and it is not even as good as Ecstar oil used in the showroom.
