Oil Weight

just got this truck a few months ago and it's time for my first oil change. I've got 34,000 miles and the book calls for either 0w-20 or 5w-20. The only 0w-20 I can find is synthetic at about $8/quart. I live in VT and it cold so I was leaning towards the 0w-20. What are alls 'yalls running for oil?

I'm in North Florida and use Synthetic 5W-30.

 

been running 5w-20 up to now 25,000 but just bought 2 cases of 0-20 to see if it really improves fuel economy like it says it does. I always used amsoil, but I think mobil 1 makes a 0-20. Doubt there is any convential oils at that weight.

Also bought 2 cases of 0-30 for my 4 runner with the 4.0....no experience yet on any benefits.

 

You will be fine with a 5w-30. The second number means it stays in grade longer at higher temps. The first number is the one that really matters in your case due to your cold winter location I'd use a 0w-20 or 0w-30 during the winter.

Ive been using 0w-20. I noticed a little increase in mileage. No problems in the cold so far.

 

Amsoil 0-30, works at -40 without issue and great when it gets hot. We occassionally see triple digits in ND, the swing in temps is amazing and a pain the ass.
