Engine oil Mobil or Shell

I use Shell Helix Ultra 5w30 in my 330i car. It also has BMW Long Life certification. I'm very satisfied with it and would recommend it to you. It also offers good value for money compared to other higher-end brands. You don't get better performance for the money you pay.

We use rotella t-6 5-40. Have put on well over a million miles between our vans and its been good. 10k intervals. We have on a 2019 with 260k. Never had any issues. Still on our original DPF. So it's safe to it's low ash oil.

Shell. Literally makes my vehicles dead silent after every oil change.

20W50 on my 2015 Toyota Hiace

I use Shell Helix Ultra 5w40 on my m52b20 E39 and I'm super satisfied

Eu nu am folosit uleiul ala, dar am pus intr-un 2.0 TDI DFGA, Shell Helix Ultra Professional AV-L 0W30 si motorul este foarte silentios.

I’ve used three oils on my bikes since the mid-2000s: Motol 300v, AMS oil, and T6.

Out of the three, I’d choose T6 for normal street riding with the occasional adrenaline run

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.

I switched to Rotella about 15 years ago after it worked good in an ej22 that was averaging a quart every 300 miles.

I've been running Mobil ESP 0w20 (VW508) since my 1st oil change at 3k miles (5 months into ownership), then another oil change at 7600 miles 10 months later. I've ran a few Auto-X events, a light educational track day (not pushing the car too much), and certainly am otherwise not shy with the throttle at all. I have also had 1k miles on my stage 1 tune since July.

You should stop using Mobil 1 oil period. Their oil is dog shit when it comes to wear protection, cold flow, burn point, and more.
