My experience with Star-Tron fuel additive...

[richard1]

First, I would like to say Thank You to everybody who replied in regards of my need to include some additive in the fuel during summer heat for keeping my engine from starving in intense summer heat(100F+).

The product doesn't bring any benefits to gasoline volatility in the climate condition mentioned above. The electric fuel pump is sucking as hard as before to supply the carbs. Same loss of power and no improvement........maybe a bit easier to start between engine shut down and start-up a few minutes apart.

The engine performs flawlessly on the freeway with the electric pump on in the hottest time of the day.......always cool (middle of the temperature gauge)....right thermostat, A/C always on at this time of the year and never a problem in early morning or early evening.

I will keep adding Star-Tron additive for the next few weeks until the heat wave will be gone here in Vegas.

To conclude..........

I may be wrong but I believe that state agencies have their own regulations on additives the distributors have to add......here in Nevada, the rules may be cheaper gas than anywhere else in USA.

It is my opinion based on the facts my car idles better in the morning and evening and in mid day I have vapor lock problems.

You are absolutely correct in your belief that various states have different regulations regarding the formulation of the fuel. Some states even vary the formulation within the state by region. Much of this is EPA-driven depending on air-quality conditions.

It sounds as if the formula that Nevada has settled on is not very suitable for hot weather and carburated cars.

today was 108+ considering the bright sun lets say maybe 5F more to be conservative.....so 113.

At 3.00PM, it is the worst I have ever experienced in the last two years.....driving up in the valley toward the mountains with both fuel pumps and the engine missing on acceleration because of starving......everything back to normal at stop light but very low RPM because engine still starving.

I stopped for an errand without having to stop the engine....it died by itself. No problem to start back but all the vapor lock was in the fuel lines barely feeding the carbs.

Members in other countries still driving on lead fuel have not have this problem. As you said some state regulations make hard on us with classic cars we still driven on a regular basis for pleasure when we have A/C.

The state of Nevada really sucks because they made the decision two years ago to ignore the need for seasoned additives to keep our classic drivable all year around.

In my neighborhood, a gentleman owned a fully restored 356 Porsche....... he drives his classic excluding summer time because of the lean gasoline problem here in Nevada.

Just to conclude......my MPG range is about 18-20 in cool weather.......right now, it is about 12-14 MPG range. It gives you a picture how volatile gasoline is here in Nevada in the worst summer months at 95-115F range.

Our state is bankrupt so they need to fill their coffers in one way or the other.......regulations on the cheapest gas in all the country to bring more taxes because you need more to go to point A to B no matter you drive a new Z or an old one

By the way, I would be curious to hear about gas quality in other warm weather states......not on the verge of bankrupt as here in Nevada.
