Hi everyone

My car is a Sentra B17 with 80,000 miles. The Nissan Dealer has used 20W50 instead of 10W30 for a long time. So for return to 10w30 (recommend for Nissan in MX), Could I use to 15w40 oil? and the next time to change oil 10w30?
Thanks

Perhaps the 20w50 was used because you live somewhere very warm. It never gets 'thick' like it would around here :)

I wouldn't go back to 10W30 at this point...you'd probably just start burning it. 10W40 if you want a marginal improvement in fuel economy...or just stick with 20W50.

Thanks d0ugmac1. But 20w50 isn't in the Manual of specifications. So, 10w40 is better?

The 40 part is a heavier/thicker oil...better lubrication at higher temps. Given that your engine grew up on 50...going to the much thinner 30 is probably not a great idea at this point.

I'm curious about the geographical location. I can't imagine a Nissan dealer recommending that oil. It technically violates emissions settings doing so. They are supposed to tow the company line as far as fuel saving oils in lighter weights.

FYI, I run 15W-40 here in Texas, won't hurt a thing, been doing it for years. You can pitch those oil recommendations in the trash as far as my concern.

I don't know why use this Motor Oil in Mexico, but I am not only me. I read in Mexican Forums that Nissan Mx use this motor oil in others cars, and They not respect the Manual. I reviewed the changes for Xtrail's mother in law and that the same motor oil.
I'm in Mexico City.
Sorry for my english
