Engine oil Shell or AMSOIL

Shell Long Ride, OP. Tested ko na 'yan and super okay niya. Been using it for a long time narin kaya im sure na goods 'yan!

I did Amsoil once a year about 8 or 7k miles since I live 3 miles from work, decided and went with Penzoil every 5k miles on 2014 4runner. is cheaper and better than toyotas mobile oil

Amsoil, i have used this oil i

n my cars, trucks, motorcycles,  lawnmower and anything else that runs on gas, it's the best.

Rotella t6 5w40 all day every day. Run it in my focus st. I noticed less oil consumption, cleaner plugs and less soot just after the second change

Amsoil signature series

10w-40 AMSOIL for metric bikes. Bike runs and shifts like new with 30k on the clock

But if high quality oil tulad ng Shell na fully synthetic, i go as high as 3k.

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

I did use the Shell T6 Rotella 5W40 for 4 OCI's and then got a misfire issue. When my mechanic was going thru the possible symptoms he asked what oil i used. When i told him it's a full synthetic deisel truck oil he shook his head and said that not a good idea. Too thick, and that could have an impact.
