PorscheKid said:Shawn, think i should change to synthetic even approaching 110,000 miles? I really wanna switch but dont want to start oil leaks.
BigAltiMan said:SHAWN, is that your setup?
If I change and discover leaks that I didn't know about, if I went back to regular would it bring it back to normal? Ide like the extra performance and longer time between changes but i dont wanna hafta start getting gaskets replaced because of it. Does the plug gap and heat range hafta be changed when switching to synthetic, and will the haynes manual tell me how to do this? Ive never heard of the heat range before...SHAWN said:I dont see why not , Synthetic will not cause oil Leaks , it will only make existing leaks worse !! I went to Synthetic at 135K ....Also remember to set plug gap at .047 in. and go to a 6 heat range ....
i really don't know if he was referring to me or just to the person who made this thread about putting in plugs... Cause I don't really see how the oil would really have an effect on those other parts unless it changes the timing or something.brazil5376 said:can someone explain the spark plug gap and heat range thing if you change to synthetic
