Engine oil Mobil or MOTUL

My 276k mile Xterra still trucks along with motul, every 3k miles.

10W-40 full synthetic Mobil 1 fixed that on my 05 Rio with the B6 Mazda engine. The sound goes away shortly after an oil change and it stays away for about 2 or 3,000 mi until the oil breaks down and it starts to make the noise again.

changing the engine oil and using motuls 10w40 fixed it and getting mileage around 40.

I replaced the company oil to motul 10w40 engine oil, the changes weren't drastic but the milage and smoothness improved over the time

I've recently started using Motul 7100 10w40. Actually I'm due for my first change and should get under it today. It's the only pull I've ever used that actually made a noticable difference in operation. The esters bond and quiet the motor to a noticable audible level. It's designed for motorcycles though and with the unique properties of this ester based oil, I'm taking a chance with carbon build up, but the protection at higher rpms it provides gives me confidence under those conditions, which is where carbon is best loosened at too. Supposedly this burns fairly clean for a synthetic, but IDK. I'm changing at 3k miles to see how it looks. May or may not extend it out, but has felt great so far in this 135k mile motor.

Mobil 1 ESp is excellent , just changed mine few days ago

Mobil Super 3000 XE 5W30, hat die Dexos2 und kostet online regelmäßig unter 30€ für 5l. Lief bei mir mit dem gleichen Motor jahrelang im Astra.

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 have been running Motul 5w30 Xclean EFE and have used Pennzoil Ultra Platinum as well.

Re oil is shit it makes the engine feel like a generator.

Using motul 5100 15w50 since last 2 oil changes
