How long to run Napa synthetic oil?

[Corollaman]

Car is a 2012 Corolla. Without doing a UOA on the oil.

I've done 7,500 in my Subaru. UOAs show it just fine. That seems like a good starting point, but will depend on your driving style...

 

[Greasymechtech]

Driving style? miles per month?

+1 on driving style. With winter upon us; I'd go say 5,500miles then SAMPLE and do UOA and go from there. My 2cents

 

[53' Stude]

Oops, forgot that you're in Washington state. My apologies sir

 

[Branson304]

I'd say it's good for around 7,500 in most conditions. But a UOA would be the only true way to tell.

These 1zz's are easy on oil. Whats the recommended OCI per MFR? My 07 is 8000km..guessing around 5k miles..but depends on habits but id see no reason not to go up to 7500 miles or more.

Pretty sure the 2012 has same oci according to Toyota as my 2013, 10k with synthetic 0w20. I've been following that since 10k. I did a change at 3k miles, then the rest have been at 10k intervals and it's just about to turn 70k. No consumption or anything.

I thought Toyota spec'd 10k on syn, 5k on dino. Any synthetic can handle that OCI.

What are your driving conditions?

OP has a 2012 Corolla, that is not a 1ZZ engine.

What does the manual say? If it says 10,000 OCI then run 10,000 miles as long as your are running the specified oil.

Follow your owner's manual

 

[WiskyBadger]

Olm, any synthetic should have no problem hitting that.

 

[Corollaman]

The manual states 1/yr or 10,000 miles with synthetic 0w-20. Since it's Napa synthetic 0w-20 I wasn't sure if it would be a good idea to go that long. I bought 20 quarts when it was on sale. My driving is about 65% highway. Thanks.

 

[Greasymechtech]

Then go the full year or 10k, whichever comes first.

 

[ryanschillinger]

That's what I would do.

Napa Synthetic is rebranded Synpower.

 

[Corollaman]

I knew that Napa synthetic was rebranded Synpower, however some people here have stated that Synpower was not as good as Mobil 1, Syntec, etc. That was why I thought maybe it was not a true 1yr 10,000 mile oil.
