Synthetic oils

My eng has been alive for 16+ years!
lift its life on 20/50 casto changed every 3,000 miles until about 5 years ago.

Now it gets changed one a year, now that i has become a trailer queen. and only go down the track maybe 10 times a year(14 sec car)

last year i switched to 5w20 Mobil 1 when from a 9.8 to a 9.6(1/8 mile track)

Syn will give you better mileage and power?????????

It will if you pushing 85psi+ with that thick stuff LOL

I won't us syn in my daily driver because it cost to much and I'm going to change it every 3000 mile whether it SYN. or NOT!!!!!!


I have a 91 Dodge Diesel that has 260,000 on it and the oil stay clean between oil changes!

If you are some one that tend to go over your 3,000 oil change , then syn my be to your advantage.

Just another opinion:tongue1:
