Mobil 1, do yo use Extended Performance?

[David in NC]

Is it worth the difference? Actually it's only about $2 more for the 5 qt. jug, but does it offer anything?
Do you extend your change periods? Thanks

They say that you can go 15000 miles with that oil. This is if you are not burning oil and if you do that miles in less than a year.
You can use their web site to find out more:

I think it's marketing BS. Use a quality oil and change every 5k.

I'd be scared to go 15k!

I'm driving 12-15k a year and might extend changes to twice a year if I had confidence in the oil. In the mean time, I'll use regular Mobil 1 and change 3 times a year, 4-5k per change.

Mobil 1 0W-20...change it every 5k with a quality filter.
140k miles now and it hasn't missed a lick.

Regular Mobil1 can go about 7500 miles....I use Mobil1 and I change my oil every 6 mo....

Without a used oil analysis there really is no way to know how far you can really go.

Our '92 was getting 8k-10k oil changes using mobile 1 10w-30. I rebuilt the motor at 285k miles due to cracked heads.

The cylinder walls still had cross hatch and the inside of the motor was still clean.

Regular Mobil 1 even since it has gone down in quality can go 10,000 miles per oil analysis I've done if you use a quality oil filter like Mobil 1, K&N or Amsoil. A quality regular oil can go 7,500 miles although I don't take it that far. That is what it says in many cars owners manuals anyway. Cars burn and gas burns much cleaner than it used to. I've never used Mobil 1 extended performance but it wouldn't surprise me if it could go 15,000. You would want to do an analysis to make sure though.

Regular Mobil 1 even since it has gone down in quality

May I ask what you mean by " since it has gone down in quality"?

You can do some searching on here for more information as the topic of synthetic oil has been covered a lot. And also a great site for oil information is www.bobistheoilguy.com. The short of it is that Mobil 1 used to be a Group IV oil but now it is considered a Group III oil.
