Engine oil AMSOIL or Lucas

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!

Amsoil Signature 5W20

I use AMSOIL engine oil and coolant in mine for the 5 years and have no issues in that department.

Using Amsoil. Nung pinalitan ko valve gasket ng 2008 Vios ko walang sludge. Gold ang loob.

I have use Amsoil European since new! 185,540km so far, and still purrs like a kitten, does not use oil, and the oil is highly rated!

I use Amsoil 20w40 in all of my semi truck motors. I change it according to what the lab says the condition of my motor and oil. I am going 100,000 miles on my over the road trucks. I go 25,000 on my power stroke and could go much farther.

I switched to 5w-30 instead of the factory spec 0w-20 and that slowed down my consumption. I use Amsoil to maximize protection with use of the "wrong" oil weight and I monitor wear with oil analysis and seem to have no change in wear from my 0w-20 use.

i use AMSOIL 0-20 in my Vezel. Runs great, maybe slightly better them LM.

I have amsoil in mine. I went 7500 once. Im sure anyone can go 10k with amsoil but it will be dark oil when u change it out lol

I used the middle one on an old 200,000KM Porsche Cayman S that was burning oil. It made it worse, smoke started coming out of the engine when the oil cap was off and I felt like the engine would soon die.
