mmccammon Posted May 26, 2019 Share Posted May 26, 2019 This may have been covered in many ways before but looking for a boiled down consensus.. if only unleaded ethanol containing fuel is available... what does one use in 1970 Monte SS?

imr Posted May 26, 2019 Share Posted May 26, 2019 the highest octane possible and dont let ethanol added fuel sit long. it damages your fuel system. Quote Link to comment Share on other sites More sharing options...

Ok.. but realistically how does one achieve this? based on how we drive these cars. ( occasionally).. and the advice to keep tank full to avoid condensation... how does one not let the fuel sit long? do additives help? Eg Stabil,? what about stp lead alternative? Is it still available? Quote Link to comment Share on other sites More sharing options...
imr Posted May 26, 2019 Share Posted May 26, 2019 the Stabilizer does help. I would prefer Rec90 fuel which many auto enthusiast and boat users use. If you have a stock big block the fuel should have enough octane. I know I let a car sit for a years and I had to clean the fuel system and on my 4 wheelers they run bad until I refuel.

DragCat Posted May 26, 2019 Share Posted May 26, 2019 Have you considered AvGas ? I know its pricey (I think $5 a gallon last time I bought some) but for a weekend driver it all works out. Smaller airports will sell it to you, some have strict rules about being metal gas cans to put fuel in some don't. We have a Sunoco that sells it along with race fuel so I get 10 gallons when I make a run. Quote Link to comment Share on other sites More sharing options...
Canuck Posted May 26, 2019 Share Posted May 26, 2019 We have this in Canada. 94 octane with no ethanol. 1 Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted May 26, 2019 Share Posted May 26, 2019 I use ethanol free in mine, there are places that sell it. If I have to use ethanol I use the additive but not twards the end of the saeson, you dont want it sitting for the winter in the car.

Leghome Posted May 27, 2019 Share Posted May 27, 2019 About every third tank on my SBC I run a can of SeaFoam thru it and when stored for the winter I make sure to have the SeaFoam in it. Quote Link to comment Share on other sites More sharing options...
