Going to synthetic!

My 02 school just hit 120,000 miles. Any negatives about switching to synthetic oil?

 

Not that I know of. Some people have claimed they have leaking issues on older vehicles that are worked in because synthetic is generally thinner.

 

I purchased 0W-30 Mobile 1 Synthetic Oil for my 05 Tacoma. I think I screwed up on the correct viscosity and wanted to know if it's ok to use this or should I return it and get 5W-30???

 

Oh god, deff go back to 5w-30 asap, cant use 0w anything in any tacoma lol, unless its a 4 cylinder, I think newer 4 cylinders use 0w-20

 

Lol yeah I made the edit when I remembered, I had a brain fart for a couple seconds lol, I used 0w-20 in my 2010 corolla xrs 2.4L when I still had it lol.... but yeah if her truck isnt a 2.7 then deff shouldn't be using 0w anything lol

 

But getting back to the subject at hand, personally I wouldn't switch to synthetic, especially on that high of milage, conventional is just fine, just use a good filter, like toyotas OEM filters.

 

Mobile 1 seems to have conflicting information with this comment and using it on older cars....

My 99 is on synthetic at 200,000miles, no worries.

For the other question 0w20 is recommended in the 05-09 v6 tundra, which has the same engine as the 05+ v6 tacoma. So if it's easier I'd just use it since you have it, then switch to 5w30 on the next oil change. I saw a pole on here that said most people use mobil 1, which is what I've always used.

 

Thank you!!!!

 

Is Mobil1 0w40 synthetic ok to use for a 2009 2.7l tacoma?

 

I thought this at first too, then several people argued that it doesn't matter when you switch to synthetic.

 

personally, idk why there should any thought put into buying oil/filters when you could just go down to the toyota dealer, pay approx $35 for a case (12 quarts) of oil specially formulated for toyota engines and filters from the dealer cost, what $6 a piece?? it just makes sense to use dealer oil/filters.

 

May be less of an issue if you keep the same grade, i.e. use 5W30 synthetic instead of 0W30.

 

Not sure if sarcastic.

0W30 is OK because it's the same viscosity as 5W30 at operating temperature. 0W20 is iffy because the oil is thinner when at operating temperature, so testing is needed to make sure it's OK. Toyota did testing on the 2.7L and found it ecked out an extra 1 mpg to make the EPA ratings look better on paper, so now 0W20 is required on the 2.7L.

 

Honestly, if i had just obtained a truck that 120,000 miles ran on standard oil I probably wouldn't change it.

No need to mess with what the engine's internals have become accustomed to.

I run synthetic but I started synthetic with my first oil change.

I don't really know what I'd consider a cutoff point to make the switch.

 

its not sarcastic, but i seriously wouldnt use 0w anything in a V6 tacoma... i didnt know if renegade had a 4 or 6 cylinder, then i later saw she has a v6... just use whats suggested in the owners manual, the manual was written for a reason is all im trying to get at.

 

60% of the time, reading the oil cap works 100% of the time.

 

I looked at Mobile 1's website and you can check to see what you should be using. It's where I read that OW was a good choice.

Reckless, thanks for the awesome link and the bad news (for me) is 0w40 is not on the list for use with a 2.7 l NA tacoma engine. But 0w20 is on the list for that engine.

It is bad news b/c I have 14 quarts of mobil 1 0w40 now I need to figure out what to do with the oil.
