Burning oil
Hey guys. I have an 87 GMC R1500 with a 305. The engine runs so well but it uses about a quart of oil every 300-400 miles. I know the proper thing to do is to replace the engine with a 94 350 i have, but i just don't have the funds to do it the way i want now. i don't wanna half ass it. is there anyway to stop or reduce the amount of oil it burns without harming the engine? It doesn't smoke on startup so i don't think it is the valve seals. you can see a little blue haze behind the truck as i go down the road. so i think it could be rings. If so can i use thicker oil? one of my dads friends told me that you could use 15w-40 and it would stop it from using oil, but could i use that without harming the engine? or even 10w-40 instead of 10w-30? Thanks Guys!! This forum rocks!
