Re: Switching to synthetic oil

I bought my 2003 Ford Ranger with 67,000 miles on it ....
I switched at the first oil change to 5-20 Mobil 1 ...
The manual says 5-20, so I stuck with it....
The only difference I see is 2-3 mpg increase ...
No leaks ....
It now has 84,000 on it ....

1966 Black/Red SS coupe .....
402 BBC
Holley Sniper EFI
Long tube headers
Tremec TKO 600
CPP 13/12 4 wheel disc brakes
Truetrac 3:73 Posi
Classic a/c
