Cost me more than $8. I decided to take the toll road and save about 10min of driving.

fiddlestickers charged me up the ass.

Fullerton is about the same distance and I wanted 110 leaded. Also I think that 76 station is closed for some type of construction.

Well I am just going by the manual. It says to use 95+ octane plus fuel additive or c12 leaded. Can't find c12 at pump so 110 should do.

Yes I understand that, not poking fun at you or anything, just wanted to make sure you don't have to run leaded gas, and the c12 only comes in a leaded formula. You have to realize some places don't have the access to high octane fuel like we do in the states. No offense meant. 👍
 
I am going to email Mike T and see what the compression ratio is in my 80 and just in general between the supreme platform engines because I'm curios as well..The c-12 is rated for engines running up to 15:1. I've seen pitted piston domes due to ping from lack of octane. Heres my quick opinion, I will not run less than 100 octane race fuel with the added lead lube in my $3k+ engine, I'll gladly take the added insurance at the extra cost just to be safe. Also VP fuel can be shipped to your doorstep anywhere in the world as well as all the other major brands being that they compete to support every application known to man
 
What is RC Max’s reasoning for leaded, not like it’s lubricating old valve seats? Does anyone know? Asking for insight not challenging it, just curiosity!

It's readily available that's why the reccomend it.

Ok, let me put this into perspective from someone who's built engines that blew $2k out the window on half a rotating assembly. Octane rating is based off basically 2 things, compression and timing. If a naturally aspirated 2.5l mercury engine spinning 15k rpm pumping 280psi compression, can live happily off 100 octane non leaded race gas with very advanced timing curve, our rc engines will be just fine with the mfg reccomended 95 octane. More octane doesn't hurt or help the engine. Just sit needed.
My issues with leaded fuel is its extremely toxic. I'm no epa fan, but the removal of lead from fuels was a smart decision. The fuel manufacturers used it, because it was the cheapest way to raise octane ratings. It did have the added benefit of helping valves seal, and keep the seats from getting pounded out of the heads. Better materials solved that issue in short order. Neither of which we need to worry about in a 2 stroke. I'll personally take a bit more of a hit in the wallet so I don't have to worry about my kids breathing in lead.
Again not being a peepee, and not insulting anyone's intelligence, but don't tell me your worried about blowing up your engine as a reason to buy 110 leaded fuel over a standard 95 or 100 non leaded fuel, when the manufacturer states in every engine manual they produce that 95 is the minimum reccomendation. Just tell us it what you want to run. Fair enough?

I'll agree that it's compression and timing I raced Ski Doo Rev sleds for a few years, still curious for my own knowledge benefit, not for battling, which is exactly why I said heres my quick opinion✌

Yeah, I'm not trying to be argumentative. Just making sure everyone understands my position. (If that makes sense?)
 
I ran rcmax on 91 for the last few years, 110 does make a difference, but may not be worth it for some.
 
Availability, okay I get that but then state the minimum octane rating and let individuals choose on what is available to them to meet those requirements. Seems they are doing a disservice to the general public. They should understand people involved in this hobby come from all walks of life and different levels of mechanical knowledge etc.

I completely understand that shelling out RC Max money on an engine is a bit daunting and people don’t want to stray from what is recommend for fear of damaging their investment. Lead is no joke, our maintenance guys are on a lead registry and have to have blood tests done because of one infrequent job they do of changing lab filters periodically.

I think if people were properly informed and knew they had a choice they’d pick unleaded naturally. That’s where I feel the misinformation is a disservice to Joe average who doesn’t necessarily have the insight of guys like Sean.
