I live in the Great White North and here in the land of ice and snow and strong beer we run mobil ! 5W30 in winter and 10W30 in summer stick to synthetics and always use toyota OE oil filters and you'll have no problems .Cherrs Aviator

 

i use amsoil 0w-30 all year round

 

Amsoil 0W30 here, year 'round. Less resistance to flow when the engine is cold, but still that great 30 weight viscosity you know and love when it warms up

It would be interesting to put some senders in the engines that are running 10W30 to see if there is any oil pressure in some spots before the engine comes up to temperature, particularly just after the filter. For my climate, Toyota recommends nothing thicker than 5W30.

 

I used Amsoil 10W30 in my 86 4X4 Xtra Cab for 248,000 miles (sold it to my brother after that).
Now I use Amsoil 0W30 with SDF57 filter in my 2003 Tundra per their recommendations. Now that they have an air filter available for it I will be using that as well. N. VA has a pretty wide variety of weather and temperature swings.
I've used Amsoil 0W30 in my Chevy van as well since it was new. My sister used it in her 6 Cyl Jeep Cherokee while stationed in Alaska and said she couldn't tell the difference between a cold morning start (-15F) and a summer day (75F) start. The engine turned just as fast. Just some food for thought...

 

My book calls for 5w 30 and i use Mobile 1 in my 2.7L. Mike

 

5w-30 year round.

 

RP 5W-30 here...I figured if the owners manual recommends it why go with something different.

 

5-30 Mobil 1 synthetic year round.
