Reviews of Shell engine oil

I live in a dusty climate I change my oil at least annually and I use Mobil one in my Volvo, Kirkland synthetic in the kids cars, and rotella in my air cooled vw.

I use Rotella T6 5W40 on my stock motor STI.

now im using shell long ride currently at 1500km and i havent feel any vibration yet and its cheaper than amsoil.

Rotella T6 15W-40 in the perfectly sized 2.5 gallon jug. I’ve run this in both LML’s since day 1 and combined it’s over 500,000 miles.

I have 2015 sportwagon tdi and use shell rotella t6 5w 40 . I have 340000 miles on and runs fine.

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.

I’ve been running shell T6 in my STI forever with no issues.

Haven’t been happier since I switched to Rotella 5w-30 synthetic, the motor purrrsss and burns a 1/4 of the oil.

T6 Rotella 5w-40 when I run test pipes on tune, the heavy weight is great for keeping oil temps down and the zinc is awesome as a friction inhibitor but is terrible for cats so when I’m going to pass emissions I run Kirkland 5w-30 full synth on stock cats.

Shell Advance Ultra for scooters. Mahal pero kalidad. Change every 2k - 2.5k. You can extend a bit more observe mo lang performance ng makina every interval.
