Engine oil Mobil or MOTUL

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've been having my Hybrid oil changes done around 12k ODO miles (~6k ICE miles). Mobil 1 Hybrid full synthetic oil. Blackstone says very little oil contamination at all and additives all still in great shape. In comments, they say I can go longer.

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 5w40 *Power* and I’m tuned. It’s really hard to heat up this oil and I have no oil coolers whatsoever and it’s been such a solid oil choice so far but I haven’t seen anyone use it except this one guy on his wrx. Highly recommend it

I use 5w-40 Motul x clean gen 2 on my built wrx. Running 5w-40 is best for added protection from ethanol dilution overtime and for warmer climates as oil gets pretty hot.

motul 5w40 8100 is great

8100 X-Clean EFE is what I ran, but yeah, it doesn't really matter

I use the Motul 8100 5w30 normally , just recently tried the 5w40 but I’m about to change it back.

Car feels slugish with the thicker oil.

I don’t like that ????????‍♂️
