Reviews of Shell engine oil

Rotella 5w-40, for no other reason than it is good oil that I can use in every internal combustion engine I own, including wet clutches.

Rotella 15w40 for mine. Never an issue and good oil reports for several hundred thousand miles.

Rotella T6 has been good to me.

Shell Rotella T6. It's marketed as heavy diesel oil, but it meets the exact same specs as mobil 1 full synthetic and just has some extra detergent like diesel oils do.

This oil in OG 9-3 that have the crankcase retrofit kits clean the entire engine very well after a few oil changes getting rid of and preventing any sludge issues. The oil even eliminated some nasty tappet noise due to low oil pressure in my 2002 9-3 after a few seconds when I bought it.

I just hit 19k miles on my 2017 390. I ride it like someone stole it. Also thousands of high revving miles on the highway.

I use nothing but Rotella T6 15w-40. It is really good oil and it is cheaper than almost anything else you can use.

Shell Advance Ultra - yung full synthetic. Mahal pero worth it. I change oil every 2.5k - 3k max.

I have been using Shell Rotella T5 for decades in big v twins. Currently 1900cc Statoliner.

Im with all these 5w40 rotella guys, just started running it in my 91 1500 with 145k miles with the 4.3tbi and she loves it, I notice a slight bump in oil pressure for sure.

I have a 2001 Forester L and I enjoy using Castrol Edge 5-30 during winter and Rotella T6 5-40 during the summer in Arizona.

I’m on rotella t6 on my ‘05 Impreza at 217k miles. Just had all the seals replaced. It has been on rotella since 132k miles. Runs really good.
