Id say maxlife when weather.is warm, Mobil super when its colder when prices are same or close.

If thier is a deal for either one, grab the cheaper.


Mobil super and Mobil super HM are guaranteed for 5k. Only Mobil super synthetic has the 7.5k oci rating from Mobil in the super line up.

I guess in my head I assumed it lasted as long as its predecessor,Mobil clean 7500. Its getting hard to keep up with the changes the oil copanies make . My mistake.

And I thought when next gen first came out, it was sm rated while white and red bottles went to sn, which caused a reduction in moly. either way, I preffer using the green bottle, seems a lil thinner, I like that its been double refined. Doesnt fly off the shelf like red bottle, so its always in stock wink

The local Walmart doesn't even stock NextGen anymore, they've got some 5w20 on clearance for 3.50 a quart.

Right now you can get the Valvoline NextGen version of Maxlife from O'Reilly and AAP effectively for free, after $20 mail-in rebate. Check the promotions forum for details. In fact, you can grab 1qt bottles if you want. Because of this promotion, I'd say grab 10 quarts, apply for rebates, and use the oil. Then use the money you saved through the rebates to produce used oil analysis reports. Maxlife Nextgen is effectively the same quality oil as Maxlife Conventional. I have been impressed with a couple of Maxlife/Maxlife NextGen reports I have seen recently. It looks like you can go 7,500 miles easily on it, unless you're engine is harsh to its oil. The only problem is that you can only get 5W30 or 10W30 weight of Maxlife NextGen from any retail store. It seems like the 5W20 weight is not available, except through Amazon or Walmart by special order.

Maxlife does NOT have seal swelling addpack , its actually seal conditioners. They made a big deal about it and recommend maxlife for use in a brand new car as well. Regardless , there is a change coming soon from Ashland I believe ......


Interesting. Maybe that explains why M1 HM worked so much better for me than maxlife. M1 openly admits swellers, uses the word in the M1 FAQ.

Here is something to consider as well: the ILSAC GF-5 and resource conserving designations.

The Mobil Super High Mileage oil is the only mass-produced high mileage oil to be fully API SN, ILSAC GF-5 and Resource Conserving satisfied. These three items can be quite important for vehicles still under warranty. Most high mileage oils are only API SN certified and not OK for resource conserving or ILSAC performance requirements.
