Engine oil Mobil or AMSOIL

Man, just changed out the oil in my 2000 Crown Victoria Police interceptor yesterday with this. I HAVE USED THIS VERY OIL for close to 20 years. My shit runs as good as it has since I first drove it out of the Orange count sheriff's dept, Parole dept. auction lot. Never use anything else.

When it comes to brands most good brands work fine like Mobil 1, Castrol, Valvoline and so on. All these oils even including the cheaper amazon brand oils have been tested by the American petroleum institute and they have a stamp on every bottle.

Since then, I've changed my oil to a low SAPS VW 504 Mobil 1 5w30 ESP X3 which according to lubrizol has superior resistance to deposit and sludge formation. At this point, I've got consumption down to around 1qt/1400 mi which is a great improvement from where it was before. Hoping for further improvements with time but pleased with progress.

I personally like Amsoil better they actually created synthetic oil but I don’t believe in 25,000 miles on it oil change if you want to run it for like 10,000 and change the filter halfway through 5000 I believe the Oil Wall hold off no problem bye just seems like a lot of miles to put on oil

AMSOIL ALL THE WAY!!!

Coyote tick is practically gone and I’ve tried Motorcraft, Penzoil, Mobil, Royal Purple, & Castrol. Amsoil is a little more $ but 100% worth it.

Amsoil 10W-30 Signature Series here. It's on the expensive side but it's 100% synthetic, tests great, and made in the USA.

I have ran Amsoil since day one on my 2016. I change oil once a year currently sitting at 156,000 miles, no issues knock on wood.

Been using amsoil for a little over a year now and it's really quiet.

I’m slowly switching to Mobil1 since I started doing oil analysis.

It has no sodium and therefore a good way to see if there is a coolant leak.

I am still on 5w30 Mobil 1...
