Just a question that I haven't been able to find a search for. I have the 1714 tuner installed on my 04 F-150 and was wondering if it would hurt the engine adding heet or Marvil Mystery Oil the 3 or 4 times a year that I add it to the fuel?
Haven't used either one yet since buying the tuner.

Thanks.

 

From what I understand from previous posts by Mike the answer is NO Additives.

I think its because they can crap up your O2 sensors. So don't do anything with additives until you get the definitive answer form Mike Troyer or someone else in the know.

Just my 2 cents worth.

 

I thought I read that you weren't supposed to but I wasn't for sure. I appreciate your response and maybe Mike will chime in when he gets back to work.

 

Hi Boomer,

Our general recommendation is no fuel additives - that does not mean that all of them are automatically garbage, or harmful.

There are some people who have used certain fuel additives for years & swear by them - for example, a fellow who used to be a good friend years ago absolutely swore by Amsoil's fuel additive, as he felt it gave him better MPG that he could quantify, and a cleaner top end inside the motor - I can't verify that, as I just don't use them.

I have to say that I simply do not have experience with a number of fuel additives, because I don't use them - as a tuner, I prefer to see what the gasoline itself is doing with no other added factors involved, so I can make a judgment on whether I feel a given fuel is a properly formulated gasoline - and a properly formulated & top quality gasoline is generally all you need, as good quality fuel will have good detergent additives, etc.

The truth is simply that I really do not have what I feel is anywhere near enough experience with long-term testing of various fuel additives to be able to tell anyone with certainty whether a given additive is going to help, hurt, or make no difference to the motor - it wold take years & years and a significant amount of $$$ and testing & tear down, etc., to determine all of that for myself - and testing fuel additives isn't what we do - so I pretty much steer clear of them altogether.

We generally recommend using the best quality fuels and steering clear of aftermarket additives as a general rule - one exception might be a good injector cleaner, perhaps, as long as you change the oil right after running that tank of fuel thru the motor.

Sorry I can't be of better help on this!

 

mike- i can attest for the amsoil furl injector cleaner- ptf i believe i've been using the past 6 years i've been sponsore by them in my 89 turbo ta, 01 dodge ram,03 f150 and now 04 e-250- the plugs and 02 sensors in the above except for the van- only 7500 miles- were all in perfect shape- no deposits on them- i use the stuff every 5 k miles when i do the oil changes- as like mikes tuning i swear by it-phil

 

Thanks for the responses. I have used the Marvel Mystery Oil and heet for years with no negative affects. My main concern was using them with the Superchips tuner.

I have read somewhere that actually the best time to use heet is in the summer because you are more apt to get water in the gas tank. But as much as I drive I probably wont have worry to much about that.

 

Hi Phil & Boomer,

I think I may have missed your real question here - so to hopefully respond a bit more appropriately, I wouldn't say that using our tuning would make a difference as to whether or not you can use the fuel additives you've traditionally been using in those vehicles, gentlemen.

 

Thanks for the response Mike. And Oh by the way the 1714 is amazing. I have just used the 87 octane mode but it is unbelievably better than stock. I think I will wait until spring when the weather clears up before trying the 91 octane. I know what would happen if I put a full tank of 91 in. It would snow a foot and I wouldn't truly get to enjoy it.
Thanks again.
Boomer
