Member JLTD (Thank You Sir!) gave me 3 gallons of Amsoil SS 5W30. My son and I were able to do an OCI in each of our trucks (he had to buy an additional qt. because his engine holds 7 qts.).tldr: is premium oil really worth premium prices for a daily ricer?
In doing some searching on the forum none of the threads really help me understand if it's worth either brand, just that there's tons of addictive in Redline, and Amsoil isn't really worth it. And this thread: https://bobistheoilguy.com/forums/threads/am-i-wasting-money-with-amsoil-schaeffers.332678/ kinda makes me think the verdict is still out on "worth".
My car has a turbo direct injection gasoline engine that's open port with an aluminum block. I drive regularly 90% of the time, and beat it somewhat hard 10%. I live in a part of the country that is cold more than hot (PA). In my engine I notice a difference if I use Redline and the highest octane Shell Gas.
Today I switched to Amsoil and it just ... I'm not impressed. I definetly feel a difference but it's not an improvement. The other thing is I hear quite often "oil is just oil, and it's not worth the price". Is that true? I really hammer this car sometimes and want it to last at least 5 years.
After about 7.5K miles his engine was down almost a qt. He bought a qt. of M1 and added it. Mine was down almost a 1/2 qt. in 2.6K miles. For some unknown reason our engines were consuming oil, which had NEVER happened before with previous OCI's.
I made a post about it here and some stated that some engines need a few OCI's with the Amsoil before it will stop consuming it. YMMV
We dumped the Amsoil and went back with Havoline Pro-DS 5W30. No oil consumption so far.
