amsoil is so much better
If you do research oil analysts here in this sub, Valvoline comes out the best.
Using high mileage oil (additives to make gaskets swell just a tad bit), used to burn almost a quart between 5k miles but now it's maybe half a quart.
I like using Amsoil because its very good at withstanding heat.
Looks real good. Valvoline R&P is in mine now.
Valvoline Restore & Protect oil, stat!
The dreaded Pentastar tick is GONE! It took about a week of regular use for the noise (on the passenger side of the top of the engine) that used to show up after idling for a few minutes to completely disappear with the new oil. I’m sure plenty of oils work fine but I went with Amsoil because my brother gave me a gift card and referral coupon for my birthday. I run 6 qts because I already have the Baxter spin-on adapter. Which requires a little more oil. The dipstick reads “low” at 5 qts whether I’m idling or checking it after the Jeep has been off for ten minutes. With 6 qts it sits right and holds a steady 30 PSI and never spikes. Such a relief!
I do like Valvoline R&P and it is in fact cleaning up two older, normally aspirated cars I have with oiling and ring issues, installed in one Lexus and one older Acura (Isuzu).
You're paying for the name.
Amsoil as an oil is trash. We used it for years and our reports were always tetering.
