Mobil 1 ESP - 12,000 miles / 1 year

Mobil put a mileage number on the Mobil 1 ESP oils. 12,000 miles / 1 year

Good to know, thanks for posting. My favorite from them.

Looks like 0w-20 got the least number of boxes checked in the first category. All others tie for the win.
0w-20 got no checks in the second category with 5w-30 the clear winner.
In the requirements category 0w-20 is the winner. 0w-40 and 5w-30 tie for losers.

What does it mean? Not sure.

Makes sense - I’ll go up to 10k or one year on the Lexus - not my favorite to change oil in anyway … dual point FI too …

 

[travis8352]

the 0w-20 changed slightly it looks like. I noticed a different revision number a while back and now its 8cst vs 7.8 iirc and -60C pour point!

 

[travis8352]

ESP is now 12,000 miles
Mobil 1 is 15,000 miles
Mobil 1 High Mileage is 15,000 miles
Mobil 1 Full Synthetic is 15,000 miles
Mobil 1 AFE is 15,000 miles
AC is 20,000 miles
T&SUV is 20,000 miles
EP is 25,000 miles
Extended Performance High Mileage is 25,000 miles

I wonder why ESP is only 12k?

 

[Snagglefoot]

Now to compare this to manufacturers OCI’s. When Chevy came out with the Gen V truck engine they dropped the typical OCI from 10,000 miles to 8,000 miles. The data was submitted by Bittogers. They also went from 6 quarts to 8 quarts. Mind you it was also when they went from 5w30 to 0w20. The new Gen V-8’s will be out next year and we can see if the combined relaxation from CAFE will tell us something interesting.

Thanks a lot for the info!
But why do we need it as a separate thread? (post #39)

Thread 'Mobil 1 ESP 0w-30 now meets SQ engine test requirements'

Nov 29, 2025

I would assume it met the engine test requirements before SQ was even a thing. Pleased to see that it still doesn’t have the API donut.

Looks like the “prior version” had 229.31, and this one does not. But, I believe 229.31 is superseded by 229.51. So, it doesn’t matter anyway.

If I had to guess, it’s the same exact stuff with a pretty new label.

I didn’t see another thread about this. So, sorry if this is a repost.

May not have the added AO or detergent level to go the distance. In the short run it could be better than anything in the Mobil 1 line.

I just figured with the ester base, it would seem more robust.

 

[Ed_Flecko]

I find it interesting that they don't mention their 0W-20 does not, apparently, meet the MB-Approval 229.72 or BMW Longlife-17 FE+. They, for obvious reasons, only mention approvals that one of their ESP oils *do* meet.

The base oil blend matters but so does the AO type, amount etc.

Because I felt like it needed its own thread. The drain interval of ESP has come into question now and then. Mobil 1 finally put a number on it. It's what I expected.

 

[chris719]

Divide most of those by 2 and that’s a reasonable OCI.

 

[Kestas]

The sump volume should be considered for these oil change interval values.

Thread 'Oil Change Formula'

Mar 2, 2003

I have been playing around with the idea of predicting a good initial oil change interval for Amsoil in new applications. This formula is based on three main variables: specific fuel consumption, sump size in comparison to a 5 quart reference sump, and power density, ie Hp/Cubic Inch. Note: for diesel engines I'd use ft-lbs of torque instead of Hp.

The simple formula I came up with, based on analysis results of Amsoil in other applications, is to change oil when total fuel consumption for the drain interval =

600 gallons * sump capacity in qts/5 qts * cubic inches/HP

If we take my new...

You have misstated the formula. Check variable 3, sump in qts again. sump capacity in qts/5 qts

 

[Japanese]

Maybe because it's designed for engines that run hotter and are hard on the oil, like German turbo engines.
Also, 12K miles is 19.3K km which is pretty good OCI in Europe. People there usually do half that OCI.

Thread 'Ted's formula'

Mar 4, 2008

I would like to publish Ted from Dixie Synthetics formula for oil change intervals. I think this formula has merit and better than mileage or time alone can ever be in managing oil changes.

The reason to publish this formula? We just finished an evaluation of oci's for a document delivery company and this formula worked over a two year period better any other scheme we know of. We did not get to the time part of any formula because these vehicles were doing sometimes 500 to 650 miles a day and the least mileage vehicles were still over 250 miles a day. We had some vehicles with an OLM and...
