If Mobil, Pennzoil and other name brands didn't have regular rebates, I would be running SuperTech no question. It is good oil.
Using SuperTech full synthetic vs name brands
- Thread starter flinter
- Start date
Maybe, a lot depends on the use of it.
If the OP actually ran out the EP to the full advertised 20K miles it might offer some ROI.
If the OP sticks to the standard OCI interval as stock an ROI is unlikely in this scenario to my mind.
Awesome! I want to see the filter cut open
I think we don't see many UOAs on Supertech because the folks saving the money aren't going to blow up the savings on a $30 UOA afterward. Since I have no problem doing that, I might just do a run of ST in my Jeep and have one done. It will be awhile, though. I've got clearance Mobil 1 AP and Shell RGT in the que for the next few changes. Still, I might have some ST cut in line and do a short run or maybe 5k. If I do it, I'll pull the cost from the entertainment budget. Lol!
Only "performance advantage" is a potential longer change interval. The higher level oils are legitimately really good oils. I have run my share of them... Pennzoil Ultra, Castrol gold bottle in particular.
Given some GDI turbo boosted motors and how they can be... Those 15-20k miles sound good... But maybe not the most realistic in certain applications and how they are run.
As noted before... That Warren Distribution made Peak had the lowest CCS at -30°F ever tested... 3,200... Lower than Amsoil Signature Series, lower than Mobil 1 AP, lower than Pennzoil Platinum... With a additive package that is on par with all of the big oils offered by Pennzoil, Valvoline and Quaker State, Castrol, Chevron Havoline...
It may only be a group III... But it is not a trailer park version of one.

I think one can also argue that the specified drain interval using an "approved oil" is also inadequate. Just look at how nasty some of these VCM engines look after 10K intervals on 0w20 synthetic per the OLM.
A "better" oil can buy you some additional margin, especially since many drivers do not change on time.
I still think most drivers who are interested in longevity are better off with 5K intervals (or less) and ignoring any OLM or UOA reports stating that the oil is good for a longer period of time.
I agree that the idea of 5k mile interval is likely a good idea in terms of longevity...
I don't believe though a Pennzoil Ultra or Mobil 1 EP will give a big difference vs a oil made by Warren Distribution... Any difference would be not be very noticeable or negligible at the end of it all.
Only thing is that they may. . . Last longer in terms of service ability. Especially in port injected vehicles.
One interesting note here... I did fuel mileage runs 40+ times... On the same stretch of one road. And I found Pennzoil Ultra and Castrol Edge gold bottle both held up fuel economy of 29.1 -29.4 in my car up to 4,000 miles. Other full synthetic oils like Valvoline, Havoline would start to drop off in fuel economy after 2,700 miles. And it was repeatable... 40+ times.
I need to find the part where a full synthetic oil made by WD claims it cuts engine wear by like 60 or 80 percent vs a industry standard.

Seems in the USA that 5k is the new 3k and 5k is very popular on this site. Just changed our Fusion at 10k (1%OLM) and I know if it had Warren oil I’d have stopped at 5k. That car is a royal pain to change oil (huge under pan on hybrids) … so I don’t want to do 5k. As for the endless TDI claims … I own 2 x 2013’s, one 2014, 2 x 2017, and one 2020.
Only one is TDI and only one is DI … so that’s lots of port injection including my 2020.
My TDI says 9K in the manual and my 2020 does too …
Average car on the road is 10+ … so there is plenty of room to choose better lubes and run longer.
People have comfort zones … we all do …

5K for me even though i've seen excellent 8-10K mile UOA using VW508. You're right, nothing tangible, just my comfort zone and i know it's irrational.
Turbo boosted motors put fuel in the fuel... Especially when it is cold out.... Dropping viscosity by a decent margin. That is evident on here by many analysis that have shown that consistently time and time again. Repeatedly.
Furthermore GDI turbo boosted motors put a lot more soot in the oil. Be one thing if the oil sump sizes were like diesels with far, far bigger sump sizes. 5-6 qt size has no where near the soot holding capacity like one that is like one in a F-250 much less over the road trucks.

Do you have one ?
To read all the analysis on here... Which is rather clear. Fuel dilution is common.... Especially in places that are colder than Corpus Christi...
Nothing wrong with those motors. They just have different considerations vs port injected motors.

My owners manual on my lone TDI says 9k …
Seriously... That does not mean it will legitimately actually make it that far.... Others recommended oils were proven to be incorrect later on.
Just like batteries... They don't last as long in Brownsville Texas as they do in Duluth Minnesota... The heat in Texas kills batteries... Up north the cooler temps seen helps them last longer...
In correlation to turbo boosted motors...
What may work in Corpus Christi.... May very well not work on Duluth Minnesota... Or even in my area..
Remember... Ford recommended 5w20... In the owners manual... Only to change that later to 5w30 because there were problems with the 5w20.

The manual calls for 5w30 …
It seems to me that the Mobil1 advertising budget must get passed on to us as the consumers.
Kirkland doesn't advertise, comes only is 2 jug boxes and is sold on line or in a warehouse. Might even be a loss leader; dunno.
I use all the oils. All good.
