Synthetic Oil preferences for 5.7 4x4's Tundra

[gregwendy]

There are a lot of different ideas about the best oil to use in the 5.7. I drive a 2008 4x4 DC with 15000 miles on it.
I understand the usage, towing, and ambient temps all come into play.

I want to get some feedback about synthetic oils, and change intervals for "normal" occasional light towing driving.

I am thinking Amsoil types oil may take a driver 10K or more to offset the price of the oil and filter.

Well folks, lets hear it!

I searched for oil comparisons on here when I first joined and found a wealth of info! Only synthetic for me (Mobil 0w 20)

mobile 1 full syn 0w20 @4kmiles for me....

[creggur]

Mobil 1 Syn 0W20 every 5k for me...

Thanks for the info. The more info. the better for all.
I am leaning towards Amsoil but Mobil 1 0-20? I thought the Toyota folks call for 5-30 w?

Clearly I need some smarting up from a few gear-heads.

Your thoughts?

[Doritos]

the oil cap says 5w20 or 0w20

I have used pennzoil platinum since start. It's great so far.

Not trying to hi-jack this thread.

I had a Tacoma and I ran Mobil 1 5w-30 but found cold starts (winter -10 degrees and below) were still hard. I'm interested in switching the new 2009 Tundra (<800 miles) to Mobil 1 0w-20 ASAP but I know you should not run synthetics during the break in period.

When is it safe to switch to synthetic?

Can I switch to Mobil 1 at the first oil change (~5k)?

Ok, back to the thread Personally, I would use Mobil 1; I know Amsoil is supposed to be the cats meow (as far as synthetic goes). I find Mobil 1 is more readily available. I (personally) also would not switch to synthetic to increase oil change intervals and save money; I would still follow the manufactorers suggested change intervals. If you want to buy synthetic to increase oil change intervals then I would consider a blend instead (which is cheaper) and still change at 5k. I buy synthetics to keep my trucks motor in tip top shape; not to extend oil change intervals. Just my two cents....

Toyota 0w-20 at the dealer 5.99qt for me.Getting 1-2 more miles per gallon when i started using it at 10k miles

Changed to Mobil 1 0W20 at the fist oil change (5000 miles), sometimes it is hard to find, I guess it's not common enough in my area, Advance Auto and NAPA usually carry it though.

Mobil 1 0w20 since the first oil change @ 5k for me as well. I get mine from Wal-Mart and just stock for couple oil changes ahead

Mobil 1, 0W-20. I have used it for 2 summers towing in 110 degree heat. Truck has 37k miles and still runs as quiet as the day I brought it home. Change every 5k miles.

Mobil 1 0W-20 Advanced Fuel Economy

[mhollack]

Im with most, Mobil 1 0w20 or Toyota 0w20 every 5k.

Mobil1 5W-20 here. Anyone have any experience with the new Castrol full synthetic? Comes in a gold bottle. Syntec was less than full synthetic. The new stuff costs more than Mobil1. Wondering.....what's the deal?

Currently Mobil 1 Full Syn 5W30 every 3 months. I might switch to Redline on the next oil change.
