Engine oil Shell or RAVENOL

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.

10W40 on my 1995 Camry

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

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

First oil change at 15,000 kms. Went for Ravenol, it’s made in Germany and seemed like a superior choice.

I had an 03 Camry from new till 2019. Had 335,000 miles when I sold it. That car got Rotella T6 5w40 since new. I still wonder how long that car would have lasted if I kept it.

Rotella T6 5w-40. No difference in fuel mileage or anything.

I run the diesel Rotella T6 5w-40. My catalytic converter decided to start throwing P0420 codes around 58k miles and I spoke to a shop that I am going to have tune my car and one of the techs said that they reformulated T6 a few years ago and it has more zinc in it than it used to and that might have had an effect on my cat and it's early demise.
