ThosL Posted January 18 Share Posted January 18 My 2.5 with 273K miles has been burning oil, I was told upping the thickness would be good, so have been adding Mobil 1 15w-50, synthetic. Someone said that conventional oil may be preferable on high mileage cars. Another piece of advice was to use Rotella 20w 50. Anyone have an objective analysis on the right oil to use?

lmdew Posted January 19 Share Posted January 19 First question is were is it burning oil from, past the piston rings, valve guide seals..... Don't know that's worth doing a leak down check, but that would provide some answers. How much is it burning? Link to comment Share on other sites More sharing options...
88SubGL Posted January 19 Share Posted January 19 Is it burning it or leaking it? Link to comment Share on other sites More sharing options...
ThosL Posted January 21 Author Share Posted January 21 It's burning, most likely the part of the engine that is hard to reach. Link to comment Share on other sites More sharing options...
mickytrus Posted January 22 Share Posted January 22 I have used lucas engine oil stabilizer in the past and it has helped tired motors. I have even put it in with 20-50. If it is cold out then go 10-40 or 15-40. read the lucas bottle. you don't have to put the whole thing in.... Getting a little harder to get conventional oil around here...
