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:
