Engine oil RED LINE or AMSOIL

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.

On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.

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.

You're paying for the name.

I don't like dominator because it's not colored have to be extra careful to not screw up the jugs or forget to put it in. At least that's what I remember, I could be wrong.
