what weight mobil 1 to run???

thinkin of switchin to synthetic in my 2012 here soon..prob use mobile 1 what weight should i use??

 

Did you look in your owners manual? It'll tell you in there.

My 07 manual recommends 5W-30, and that's what I use.

 

Its also on the cap..530 is what i use

 

alright didnt know if anyone usually switched once on synthetic...

 

Since I'm in a moderate climate I use M1 0w30, but on the v6 that's as thin as I'll go. If I towed (more than a jon boat), wheeled, or lived down south I'd use 5w30.

The difference in mileage between 5w30 and 0w30 disappear after about 2 minutes past a cold start fwiw.

 

The lower the first number, the better the cold start protection, even in the summer. A full synthetic 0W-30 starts as a 30 weight oil then has viscosity index improvers added to let the oil flow like a 0W when cold. If your engine calls for 5W-30 you can safely use 0W-30 all year.

 

manual says 0w-20 for a 4 cyl and 5w-30 for the v6

 

That's what I was hoping for. Save a little fuel on startup, plus cut down cold start wear because the oil system gets flow so fast.

I just wouldn't use it on a habitually hardworking engine because 0w30 needs more VI than 5w30 and doesn't stay in viscosity range as long under high stress (in theory). For a daily driver though, why not...

 

My truck is almost all Mobil 1 now. Engine uses 5/30, rear axle M1 whatever the closest viscosity is, power steering is M1 ATF, Front wheel bearing M1 grease and as of tonight the automatic transmission is double filtered and mobil 1 atf.

Check the manual or filler cap as already mentioned. You might want to buy a good filter wrench. I don't have a 2012, being a 2010 I have the spin on filter. I believe yours takes the similar wrench as a Corolla. I forgot what brand it was, but I got an all aluminum tight fit wrench for the car. Was about $20. Part number is toy 0640 or something similar. The auto parts stores didn't stock the exact size.

Not to highjack the thread guys but when should you change your oil. When i went to the dealer when i first got the truck it went from 3k to 5k back to 3k and its 5k and and im at 23k. Used my last free oil change last month. I should be ok at changing it at 5k right.

 

I don't need a wrench. My grip would give Chuck Norris the shivers.

No really, a little while ago a buddy of mine took his car to get his oil changed (that I'd tightened the filter onto). They complained because it took 3 guys a half hour to get the filter off. Oops...

M1 ATF is compatible with Toyota WS??

Yes, 5k miles is what Toyota says to do if you have a v6.

 

Right. 5000 miles under normal driving conditions.

 

Technically per Toyota no. After spending a bunch of time reading about WS and comparing specs to M1 atf, I decided the synthetic M1 atf was a better choice than the non synthetic WS.

So far, the truck seems better in regards to shifting and also the movement of the shift lever out of park is no longer notchy.

From what I read, there is nothing special about WS. Just a very low viscosity ATF. The M1 is more viscous but not much. When you compare other aftermarket fluids that are WS rated, they are also more viscous than WS.

The M1 was previously an approved atf for the Type IV fluid, then that was no longer listed. The likelihood that the tranny manufacturer redisgned all the fluid paths for less viscous fluid is unlikely.

Most probable reason they use WS is for fuel mileage.

FWIW, the atf that I drained out had 25000 miles on it. It was noticeably darker than new WS and also the M1.
