Engine oil Mobil or Shell

I like motul for my Merc. But I just swapped in shell rotella 5w-40. Had some tick on startup and now the car feels smoother and quieter overall. I have a 92 with 73k

I’ve ran mobil1 5w30 for a few years now with oem filter on my 1990

I use 10w40 also from Mobil 1 high mileage. A lot of our engines will have a tick on start up or once hot, if so with your Motul, switch brands to another top tier on next oil change and see if your engine likes that brand more.

Shell high mileage oil.

I changed oil with 80% Mobil 1 high mileage and 20% Lucas high mileage oil stabilizer in it, did better than just Mobil 1 high mileage 5w20 alone in summer, (very hot temperature).

M1 ESP is arguably the best oil out there. It does not shear fast, doesnt degrade with 5% fuel dilution.

I run Mobil in all my cars. The regular 0W-40 is cheap and easy to get, as is the 5W-30 ESP for the RS3. Right from Walmart.

Rotella T6 15W-40. I’ve used it in all my bikes, cars, lawnmower. It’s the best option if you own lots of motors. Just change it frequently.

Installed new oil and filter, plus BG oil flush, ran at idle for 30 minutes (warm-up, plus 15 minutes). Changed oil and filter again, using Mobil 5W40 Euro oil.

I just go to crappy Grease Monkey and do full synthetic Mobil 1 for like $100.00. Then I drive home, and double check their work.
