Heet red vs yellow bottle for car

I was told by a parts store person years ago that if you had a carborated motor yellow bottle was fine,if you had a fuel injected motor to use isopropyl heat as the yellow bottle or methanol heat would pit your injectors.I use red bottle it costs a little more but car repairs are much more spendy.

They are slightly different. The yellow Heet contains methanol. The red Heet contains isopropyl (rubbing) alcohol. Yellow Heet has been sold for over 50 years. The red Heet is newer. As antifreeze, both do the job effectively. The red performs slightly better in extreme cold conditions, and tends to cost a little more.
If you're using Heet as fuel (in an alcohol stove), the yellow is the more commonly chosen, but either will work. Using the red as stove fuel can lead to soot and residue. Yellow Heet burns clean.
Hope this helps.

For snowmachines with EFI, you need to use the RED Heet.

Rated 5 out of 5 by Rihcardg from Water in gas My truck started to sputter and stumble while trying to accelerate. It got progressively worse over a few days to the point it would die every time I pressed the pedal. I was beating my head against the wall; changed the fuel filter, tps, map, serviced the map, etc. I was talking with the guys at the auto parts store and they suggested a bottle of heet. In all my 30 years of driving, I've never had an issue with bad gas before, but at this point I'll try anything. I put one bottle of heet into 25 gallons of 92 octane. After 2 hours... My truck runs great.

Arizona can have extremes when it comes to weather, Sunny and 70* one day, and several inches of snow the next, and then our fuel station attendants allowing water to enter the fuel drop stations entering the underground tanks. We that live here in Central Arizona have seen too many fuel systems and tanks loaded with up to a gallon of water. In lieu of removing fuel tanks, we have found that removing the water with a sparkless transfer device and adding HEET has brought these vehicles back to life!

Rated 5 out of 5 by vette84 from HEET gas line antifreeze is a winter necessity My Chevrolet is hard to start when the outside temperature is below freezing and when it does start and I drive down the road the engine misfires . I added one bottle of HEET gas line antifreeze and water remover in to the full gas tank and after driving 20 miles to work the engine smoothed out and did not have a engine miss. The vehicle started right up the next morning at a well below freezing temperature with no engine miss. Great product that works.

Rated 1 out of 5 by FrustratedInChicago from Foil seal clogged my gas tank intake I have used Heet for some time. I was always perplexed why the foil seal on the opening didn't have a pull tab to remove it. Many times I have to use my car key or a pen to open the foil seal. My car recently stalled - my mechanic had to remove my gas tank and remove the foil seal that must have come off while I was pouring the Heet into my gas tank. Now I have an expensive vehicle repair bill thanks to the poorly designed foil seal on the Heet bottles.

Rated 4 out of 5 by Polish don from Worked well I put in my 2015 Dodge just before we go hit with some Sub-Zero temps. Worked as advertised. Only issue I had was that either the gas I put in was more then the product could handle or I needed more product. Because when I got down below 1/2 tank, the car started to act up. I had to refuel and add some additional fuel deicer and the problem resolved

Rated 5 out of 5 by Guy1 from HEET takes a bite out of winters bark! This product came through again to save yet another vehicle from excess moisture in the gas system. Within a few hours of pouring one bottle into the gas tank this HEET made the car run smoothly again. No more stalling or rough idling in traffic. I always use this product when a problem crops up. I also use it preventively whenever I'm concerned about the quality of gas that may have been added to a vehicle. Either way this product actually works and has given satisfactory performance each and every time that I have used it.

Rated 5 out of 5 by KCwildguy from A must have for winter I use this product in every fuel tank I own. If you are storing gasoline for any length of time, water condensation forms and can freeze. HEET keeps this from happening, extending the life of your vehicle. I highly recommend HEET in every garage.

Which HEET should I use?

Is the yellow or red Heet better?

Can you put too much HEET in your gas tank?

Should you put HEET in your car?
