If this has been discussed a million times, then pardon my repetition. I am curious about the validity of the claims of AFE. Any actual users out there who can attest to it? No M1 bashing please, I am simply curious as it seems that I **could** glean a free tank per year according to the website. This is from the M1 AFE calculator on the M1 site using my FX4 as input.

This is the only Mobil product I would try.

Good UOAs as well, but I do understand they may overestimate a bit but no big deal.

I like seeing my mileage increase, even if it is a small amount.

It's all in the fine print. All things equal,lower viscosity is better mpg than higher viscosity.

Is there really that much difference between 5W-20 and 0W-20?

Oils can be very different.

That is why there is so much segmentation amongst brands.

If you compare, by watching alone, the difference in pouring Toyota or Idemitsu 0W20 compared to pouring Pennzoil Ultra SN 5W20, you would be led to believe one is much thinner.

And thinner means less rotational drag.

Like running through water or running through, um, thicker water.

There can be. Viscosity index plays a big role in drag at start up,then viscosity at operating temp.
All things considered less drag means less fuel consumption.

You have a good thing going with MS5K. Why even bother with a more expensive option? You won't see much of a bump in fuel economy at all.

I am not considering switching to M1 in my FX4, I am just curious about the claims about AFE (extending knowledge you know). My wife may be buying a new car soon and I wanted to learn a bit about AFE in the event it becomes an oil of choice for the new car.

I've mentioned this a few times before in other threads...0-20 afe decreased mpg in my civic as it approached 200k miles. This was vs 5w-20 m1 EP & m1. This was a well worn engine...so YMMV...literally.

As far as mpg goes, I wish there was more emphasis on lighter cars and less on lighter oils.

why not consider it? let us know. you are one of the few here that performs long term proof giving test with your truck. maybe consider using AFE 0w20 for the next year and let us know if it does in fact improve your mileage and retain long drain intervals like MS5K.

I feel very confident the AFE could go 10K like the MS5K, but I have too much MS5K to switch grin!! I bought gallons of it when OR and AZ had the specials going so that I could complete my experiment. On the other hand, the stash that I bought for my Dad could be "converted" to AFE (he no longer needs it since his truck was totaled). Hmmmmm...always a decision to be made here on BITOG wink

M1 AFE 0W-20 is an improvement in fuel economy over most 5W-20's but as others have alluded, the ultra high VI OEM 0W-20's such as the Mobil made Toyota 0W-20 and the Idemitsu made Mazda 0W-20 are the oils to use to maximize fuel economy.
For example TGMO is 35% lighter at 32F, 25% lighter at room temperature and still significantly lighter at normal operating temp's compared to AFE.

No Mobil is claiming 2% over a 5W-20 dino.

they are claiming going from a 5W-20 to a 0W-30 is moving "from a higher viscosity oil" ?
