Mobil 1 Extended Performance for 2010 Corolla?

[1JCB]

We recently purchased a low mileage (20k) 2010 Corolla with the 1.8 liter engine. The car is driven pretty gently, with a mix of in town and highway miles. Would Mobil 1 Extended Performance 5w20 and the Fram Ultra filter allow 10,000 mile oil changes without problems?

20 years ago I tried 10,000 mile oil changes with Mobil 1 5w30 on our 1999 Escort and saw sludge buildup under the valve train. The sludge cleared up after I switched to 5,000 mile changes.

Are the new oil formulations enough better to safely allow 10,000 miles? Or should I stick with 5,000 miles?

Absolutely. I run castrol edge or Mobil 1 Extended Performance and ultras in almost everything I own and all on 10k oci.

Not to exceed 1 year between oil changes, and you're fine... usually. The only exception is when your trips are mostly under 10 miles each, where the oil doesn't warm up enough.
With Mobil 1 Extended Performance, technically you could go up to 15k miles or 1 year, and the Ultra will do up to 20k miles, although all that is really only possible if your oil warms up enough more than 90% of your trips. Taking it a step further, M1 Annual Protection will go 20k or 1 year. Mobil says M1 Annual is their best, if you want that. Better anti-oxidants they claim, and they're likely telling us the truth, not just marketing fluff.

As long as the car gets up to temp every now and then you should be fine for a year. Change out after 1 year regardless. If you want added peace of mind you can have the oil analyzed.

Toyota says you can use any synthetic for 10k with no problem

If the engine is relatively clean, 10K OCIs are fine. Otherwise buy a cheaper brand and run a couple of 5K OCIs first.

Nice find. Those engines are very easy on oil, so use any name brand synthetic. You don't need an extended life oil for 10K OCI.

I run Mobil 1 Extended Performance 0w20 in the wife's 2010 Corolla & change it yearly......She puts right around 13,000 miles a year on it.

I had to reseal the timing cover right around the 100,000 mile mark, The engine was VERY clean without a spot of sludge. Just a slight yellow tint on the engine components.

I have a 2010 1.8L as well. I run Mobil 1 Advanced Fuel Economy 0w20 or EP and Denso filters around 7.5K-8K miles. No oil loss, no problems, 181K miles, 33-35MPG.

My 40 year experience with Mobil 1 oils at 10K OCIs have never produced any sludge or varnish in various Ford engines including Escorts.

The 1.8's are super easy on oil. You should be easily good to go with that combo.

I realize you mentioned "usually" but how important is it not to exceed 1 year between oil changes?r

What if you put much less miles than the recommended oci in one year, and you are not short tripping it, do you think it will be ok to extend the oci to 2 or 3 years?

Think I'm on about 5 years now. Seems OK, 4WIW.

50/50 SAE40/20W-40 Group1 mineral.

Thanks to all for the positive feedback. It looks like 10,000 miles or 1 year is OK for this engine.

Yes, you're right, I think the chemistry would hold up. If you're not stressing the oil out, which is what the 1-year arbitrary limit is trying to counter, sure yes. Look for a rise in viscosity to indicate that oxidation is beginning to take over, maybe about a +1.5 cSt rise in KV100 would be time to change the oil (if that is known, it could tell you when to change).
-----------Fleet vehicle managers who try to save by going long on oil changes say their big problem is drivers not checking oil level over that long a period of time.
-----------Some Chevy Volt and other plug-in hybrid owners report their engines only run once a month, so they look to go 2 or 3 years! I'd definitely use a premium oil like M1 Annual Protection or a Ravenol oil in those.

What are the relative merits of Mobil 1 Extended Performance 0w20 vs 5w-20 for this engine?

The car is garage kept, and we have mild Winters here in TN, so even in the Winter a cold start is 45 degrees.

 

[PimTac]

You can run either grade. 45 degrees is not even cold.

Yes Mobil 1 Extended Performance and a Fram Ultra filter will go 10k in your mixed usage, if it reaches full temperature on a regular basis.
I'm questioning the choice of grade... does Toyota spec 5w20 for the 2010 Corolla?

 

[1JCB]

The owners manual says either 5w-20 or 0w-20 should be used.

0w20 will contain more actual group III+ and Group IV synthetic lubricants. 5w20 should be a little cheaper. For 45F cold starts, take your pic, it really doesn't matter.
