I have an 06 tundra dc sr5 with 13,000 miles and live in so cal. don't do much hauling and the weather is always sunny. what type of oil should i be going with?
i think the higher the #'s (i.e. 10w40) is for older cars with leaks, am i right?...
I run it because that's what Toyota recommends. There are stretches here
where it gets pretty damn hot during the summer and I still run it. You
should check out the website www.bobistheoilguy.com
The site really goes into detail about engine oil and differentiates myths and
facts. If you're really bored do a search of "Engine Oil Filter Study". A lot
of information on oil filters and oil filter ratings from someone who obviously
had a lot of time on their hands.
I live in Guam, it's between 85-93 degrees here year round. I run synthetic 5W-30 in my truck. It's what Toyota calls for. Just tipped over 60K miles on my '03 I've owned since new and have always used synthetic and always Toyota oil filters.
Living in LA, you'll probably not notice any difference in using 5w-30 or 10w-30. The "w" weight is for "Winter" weight, and LA doesn't really have one of those. lol
If you saw temps under 0'C, then you may want to read into the Winter weight #'s a little more.
