Default fuel makes engine run cooler????

Hey guys, got a question. I switched fuels (from backyard basher 20% to maxys fuel 20%) and i've noticed that the engine temp is considerably cooler. I thought it may have been my imagination, but my father in law and me both have hpi rs4 rtr3's and we were running about 230-250 degrees with the backyard basher fuel. today is the first day we switched over and i know that i would have to re tune the engine. but i noticed that the temp never got over 200 degrees. could the fuel really change the engine temp that drastically? Like i said its on both our cars so its not like its an isolated occurance. the only major diff between my car and his is that i have a different pipe.

Also, i am thinking of getting another pipe for both cars. what do you suggest? Its an hpi rs4 rtr3.

The different oil content can help with cooling the engine as might be a help in your case. Check the 2 containers and you should notice your new fuel has a higher oil content. Other than that the only other thing that would drop the temp would be the nitro content being less.

But, what has the weather been like in your area lately. Has it been cooler than normal, etc....?

why did they dont use regular gas fuel for real cars on our rc and instead they use methanol? our 2 stroke engines are the mini me of the ones on real motorcycles right? can we just use real gas then add castor oil, etc to be used on our rc engines?

No! Do not use real gas..

These are two totally different beasts. Nitro cars are Nitro cars, Gasoline cars are Gasoline cars. They can't be mixed!

To me with my engines the less oil content the cooler the engine runs. But that has alot to do with tuning. Before we started mixing our own fuel , I switched from Trinity monster fuel to Trinity platinum, which is only about 8% oil content ,and engine temps dropped 20 degrees. I mix my own fuel now and use 8% Klotz, 2 stroke syn. oil.

no change in weather. i usually run the cars after 5:00pm (time i get off of work). I live in Miami so its ALWAYS hot, but by 6:00pm its cooled down a little. The backyard basher has a 16% oil content and the maxys fuel has 18%.

I don't think it's a matter of more oil or not,what's more important is the type of oil used.

I would use the Platinum blend all the time, if I was'nt hooked up with VP Racing Fuels. I use their Alky and Nitro and blend it myself.
