Engine oil Shell or AMSOIL

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.

As an avid amsoil user I am bought into the brand. Every product I have has made my equipment run better. I run a small farm and have amsoil in every fluid in all of my vehicles. If you are in the preferred deal it really isn't that much more expensive than regular oil.

My L5P doesn't tick with amsoil. My 5.3 you can't hear the lifters with amsoil. I have a 5.3 that has 300k on it and never had a motor problem with it and it has been pure amsoil since 35k miles.

I have a 2017 1500 5.7 that’s had nothing but Amsoil SS 0W-20. Purrs like a kitten. I have done multiple used oil analysis on all my family’s vehicles. They all use SS OW-20 and the analysis come back with very positive results. I will never use anything other than Amsoil.

At 156k after cam/lifter replaced I started doing DIY Amsoil changes. At 255k I put in a crate engine. If Amsoil made a difference it got the bottom half of the engine to 250k miles from 156k so about 13? oil changes. I think the cost difference is minimal so yes, I think it was worth it. Delaying $10k for new engine is the goal.

Mopar oil filter, amsoil 0w20, don’t over torque filter housing.

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.

Was using motorcraft, switched over to Amsoil. Cost is the same maybe a couple dollars more.

Shell engine oil gamit ko sa click ko, mag 5 years pero wala naman naging problema

Get the shell advance ultra for scooters. You wont regret it.

After not being very impressed with Amsoil 5W-30 after a 5,000 mile oil analysis, I'm going to see how this stuff looks after 5K.
