Add quart of oil every 800 miles?
hey everyone, I just discovered this forum and there seems to be some pretty knowledgable people here hah, so i have a question..
I have a '98 M3 with about 124K miles on it. I just recently was told that every 800 miles i should add a quart or so oil to my car because due to the performance engine, oil tends to burn a lot quicker than other cars. is this accurate? i just went over the 800 mile mark and checked my oil and it looked about right, no problems or anything. what do yall think?
and btw, im using synthetic 5W-30 oil. is that my best bet for oil? what blend/viscocity rating does everyone else use? thanks!
