10w 30 v 5w; any difference?

Owner's manual calls for 5w 30 which I've used to change my oil - using synthetic. My boss bought some Mobil one 10w synthetic on sale and offered it to me. Is it alright to use the 10? I have 141k on my taco: 01' prerunner, ; cycl. 2.7

 

Go for it.

 

Yep, go for it. You will be just fine.

 

The 10w30 is just thicker oil at low temp compared to 5w30. I dont how cold it gets in San Francisco but 10w30 oil shouldnt be a problem

 

No noticeable difference whatsoever.

I use ONLY Rotella synthetic T6 5-40 in mine, best oil out there, go to Bob the oil guys website and look it up!

 

I concur. Especially in the summer the thicker oil will be OK.

 

Your truck gon' blow up.

 

The 01 owner's manual shows both, depending on anticipated temprature range, but with a ton of overlap. Dont' have it in front of me, but bascically, you'd only have to use 5 if you had regularly freezing, and only have to use 10 if you were regularly over 100 or desert.

 

I Never run 10-w30 conventional because the oil industry uses this grade in particular to get rid of its low grade bases( I, II ) . Other conventional grades are usually (II & III's) but since your running synthetic it should be Almost all grade(IV)bases.

 

Have you done uoa's to prove its the best? Even if you compair the same engines I can almost be certain all will have different wear numbers.

 

unless it makes a mpg difference that is worth it or you're keeping your engine 500K miles it's a waste of money. I've known people that used conventional, average cheap motor oil and tore their engines down after $200K miles and it looked great. I'm not advocating conventional oil, just making a point.

 

so with 250k miles 5w-30 or 10-30 2.7 Tacoma? burns a quart every 1500 miles

 

When I lived in San Diego I was at a Toyota dealer and their oil was on sale. A mech told me to use 10W30 and that it would NOT hurt the engine at all.

 

Fix your rings and seals and it doesn't matter what oil you run.
