datzenmike Posted June 15, 2010 Report Share Posted June 15, 2010 Generally you would be good from -10F to over 100 F. If your driving temps never drop below 50F year round, you could use 140. Quote Link to comment
HRH Posted June 16, 2010 Report Share Posted June 16, 2010 75/80w90 is perfectly fine for most Datsun uses. Unless it's super hot or you're tracking it, 140 isn't necessary. The bay area is pretty balmy, I'd run 75-90 for sure. If it was Phoenix, I might opt for 140. Quote Link to comment
