Anyone use fuel additives??

I received my last free oil change at the dealership today and they suggested a BG product that fights ethanol damage. I was warned about ethanol damage to my 20 year old Trans Am so I add an additive every once in awhile. I would think our newer Challengers would NOT need this stuff so I did not buy anything.
Am I wrong on this? If you add an additive, what do you use? (I use the Lucas brand for my T/A).

 

Our cars are designed for ethanol to a certain %. I have never ran addatives and never will in any of my new vehicles.

That said, on my other motors i run non ethanol gas. Like mowers, chainsaw etc..

 

Today's vehicles are engineered to run ethanol.
I have been told by technicians that a person runs a chance of damaging an engine of today if fuel additives are used.
I run Sea Foam in all my lawn equipment and used it in pre-2006 engines as well.
About the only service you need is a fuel rail cleaning.
On direct injection engines a person needs to have an induction cleaning performed at around the 30,000 mile interval.

 

I don't use any fuel additives. I've also been told that there's a greater risk than reward with many of them. I only run Top Tier gas in my vehicles in an effort to keep the injectors - and everything else - as clean as possible.

Having said that ... I know a guy that works for BG and he swears by the stuff.


Speaking of gas ... don't over-think it. Just give the vehicle what the ECM is expecting. Unless you have a tune ... 89 octane for the 5.7 and 93 octane for the 6.4. Back in 1999 we bought a Jeep Grand Cherokee that was a wonderful vehicle. When I took it in a couple of weeks later, I mentioned that the vehicle seemed to have a slight stumble. The service manager asked me what kind of gas I was using and I answered, "only name brand premium." He quickly said, "that's your problem. Run a tank of 87 through it and let me know how it responds." Totally solved the stumble. The ECM was expecting 87 octane and 93 octane was causing the stumble. My Toro mower is the same way. With premium you have to give it a squirt of starter spray. With regular it will start on the first pull.

 

I run 89 non ethanol in all my lawn equipment. Works great

 

I run 89 Non Ethanol in fact Filled up today now its 2.10 more per gallon then what I paid in Jan before the 20th...
So what was 33.00 per tank today was Nearly 87.00 good think I get 29 to 30mpg per tank.

Once every 6 months I do run STP Injector Cleaner in a Tank nothing else I tired the Octane etc., waste of money.

 

Stabil 360 marine fuel stabilizer.300k on my 5.7 hemis and never a stumble.$20 qt on amazon.Use it in my 1977 350cid chevy.All my lawn equipment and chainsaws.Does it actually work? I may never know....

 

^^ That's the thing. How would you ever know unless you tear down things.
I see demonstrations on YouTube and most of them say it helps a bit.

I'm just leery with my 'new' car. I'm like Wizard of Iz above and put in the 89 octane from Chevron, BP or other major oil company and it performs fine. Like I mentioned earlier I don't worry about adding it to my older rides. No issues but is it doing anything?? It's certainly not a price consideration for as little as I drive (other than road trips).

 

Fuel additives are fine, just don't go ape-shit with them. Non-ethanol fuel is the way to go, but its pricey. Our area is limited to 89 octane, which is fine for my lowly 5.7 HEMI with performance numbers that match a street version 426 HEMI.

 

^^^ I always appreciate your post bringing that point up about the mainly equal performance numbers between the first gen 426 and the 5.7 Hemi of today. Of course our rides are so much better as a whole, from braking to comfort. While I really enjoyed my first gen 'Cuda, this R/T is wonderful. It would be cool to have both in my garage but the cost has become prohibitive for me personally.
