I recently moved to San Antonio from North Carolina. I have an 84 1500 with a 350 engine I am no mechanic but I know a little about alot. And just wanted to see if there are any shops or groups etc around the San Antonio area that if need be I can stop by to get someone to look at my trucks performance. just curious what everyone uses for there 350 as far as motor oil. Also why is there little to no gas stations with non ethanol fuel. I feel my trucks carburetor hates ethanol. Which additbes do you recommend? Thanks !
