1998 Nissan Altima Question: RECOMMENDED OIL WEIGHT

MY 98 NISSAN ALTIMA IS GETTING A replacement with a 78000 MILE ENGINE. MECHANIC IS PLANNING ON PUTTING IN 20/50 OIL VERSUS 30? my bad engine had that heavy weight because it was worn out. WHY would he make choice for such heavy weight? I LIVE IN FLORIDA AND HE CLAIMS ITS BETTER BUT????? -
Answer 1
20W50 is too much for that engine. Even in FL 10W40 is enough for your Nissan. Use a good quality oil, like Pennzoil and replace it every 3K miles. Zee -
