10w30 or 5w30 in New England?

[will1780]

Winters can be brutal and summers are usually hot and humid. which is the better choice? I drive roughly about 1000 miles a month with about 50/50 mix of hwy and local driving. my car is a 1999 mazda 626 4 cyl. with 100k on the odometer.
Thanks and love the forum

How about 10w-30 in the warmer months and 5w-30 in the cooler months?
Also 10w-30 is good down to 0 degrees f.

A 10w/30 syn would work all year but then so woulda syn 5w/30 but... ..may have a bit higher consumption ,or not.

Why don't you follow what the owner manual says. You can't go wrong...

5w30 the year around with decent OCIs is the ticket!

Then what is the point of bothering to have this website?

Yes, TallPaul. There are dragons still out there that need to be slayed (or is that "slain"

) .


Given you climate and annual mileage, I would do 6 month OCIs with either. You obviously don't do too much short trip driving, so the tolls of cold starts are minimal compared to your long mileage needs. Spring and Fall are great times to purge the insult of the extreme seasons.
