0W20 AFE and 0W20 EP

[wrf01a]

I noticed at Wal-Mart the other day that 0W20 AFE and 0W20 EP are the same price at Wal-Mart. I have used 0W20 AFE in both my 2013 Hyundai Sonata and in my 2012 Honda Civic exclusively since the first oil change.

My question is would there be any benefit to switch?

The 2013 Sonata gets an oil change every 6 months due to warranty. Mileage on the car typically ranges between 4500 - 5000 miles.

The 2012 Civic gets its oil change whenever the Oil Monitor indicates 20% Oil Life remaining. That typically ranges between 8000 to 8500 miles, between 9 and 10-months.

So from a "protecting the engine" position would there be any benefit to switching?

It would not hurt anything, but I did not see a big difference in performance between the two in my 2010 FX4. EP is supposed to be a longer drain oil than AFE, but it did not seem to perform that way. At the same price, I would use the EP with no worries.

For your oil change intervals the regular M1 is a better oil.

 

[tig1]

I have used 0-20 AFE for years with very good results at 10K OCIs.

 

[Rolla07]

To answer your question...No.

EP is useful for longer drain intervals. In my non scientific test I preffered AFE but I use short intervals so pointless for me.

Reason ?

EP has more PAO than regular and HM Mobil synthetic. This is the main reason I preferred EP, especially when I can get it for the same price.

Is there any negative about EP compares with regular M1 ? To me AFE is a marketing ploy of Mobil, if there are M1 0W20 and 0W30 and AFE 0W20 and 0W30, then AFE's are real deals but they aren't.

 

[Chewie]

I would pick the EP because fact: it has a higher quality base oil (60-70% PAO), which is part of what allows for the longer drain interval. That seems to be some of the only concrete evidence in this discussion, everything else is pretty much opinion. Fuel economy differences are essentially unmeasurable. Price being equal, why not go with a higher quality product?

Regular M1 does not come in 0w-20, though I'm sure the 5w-20 would do fine. At Wally World they all cost the same so why not use EP. At worst it's no better and at best it will provide added protection.

XOM cuts the phos and zinc in AFE oils to get the low temp performance. They put them back in EP 0W. What does that tell you?

I don't know what that is telling me. Please, take me to school! Not being sarcastic, I would like to know.

I prefer the M1-EP in a GDI engine. I run it in my Mazda and have been impressed with the low NOACK and burnoff rate. Below are the specs right off the Mobil 1 site as of today (2016).

More Calcium, Magnesium, Phosphorous, and Zinc anti-wear in the EP by a good margin. 1 more TBN point at 9.0 (see below links to VOA)

I also have found that the NOACK of Mobil 1 is reported to be lower than almost all the other synthetics. This means considerably less burn-off, PCV issues, valve deposits, and engine oil consumption.
Since some of the posts were from new-comers:

If is the same price pick the premium EP.

All there is are extra additives added.

Fixed it for ya

tig1 and Rolla07 said all that needs to be said on the subject.



Extended drains? EP

Not extended drains = AFE or reggie

I know it can seem endless worrysome because of hundreds of oil choices, but it doesnt have to be complex., look in owner manual for grade.....find a brand/type that works for you and your engine and there you go.....who said that on here 'wherever you go, there you are"?


It took me about 15 years of being around cars, trucks, semis, motorcycles, planes to find a motor oil I like. About half of that has been here on BITOG. Of course, the way luck can be- they will reformulate, cancel it or go bankrupt.

I would also use the EP formulation in a DI or Turbo DI engine compared to the AFE. As the MoleK has stated, formulations can change without notice. See the difference between the 2011 VOA of 0w20 posted above and the one done by PQIA in 2014.

Agree. I'm running this in the Skyactiv 2.0 and there is no noticeable oil loss at all using the EP 0w20. I was able to confirm the NOACK for EP 0w20 is 10%. Only Amsoil 0w20 matches that number, which is also 10%. M1 EP 0w20 has the lowest NOACK of all the 0w20's on the market. It's advantage over the Amsoil is the lower SA, which is .8%.

Same here.

 

[OVERKILL]

EP is also a better "value" than the AFE at the same price due to the higher amount of PAO on it.

^true.
