I have a question, and it deals with gasoline types and what to use. I know that as of now I use 93 octane and only purchase gas from the same two stations wither it be a Speedway, or Shell. My question is as follows, I know that once you start using a synthetic oil, you shouldn't go back to conventional oil again. Now here is were the question is, being that 93 octane is the highest rated fuel you can purchase at a market, how much damage can we do if we use a octane booster or fuel injector cleaners that contain boost in it. I know some boosters only contain maybe 3points, so going from 93 octane to 96 octane street use, is damage occurring? I'm asking cause what I would like to know is what additives can we use that will safely clean the injectors and fuel system. Much like how cars have the engine treatments that you just add to the oil, are those safe to use to we have a version of that we can run for 600 miles and then drain for sludge? And build up? Regulations stop gas stations from adding additives each one is tha same as the next either it be 89, 90, 91, 93 all have the same....just asking...
Octane Levels
The most common levels of octane grade are 87 (regular), 89 (mid-grade) and 91-93 (premium). The octane number of the gasolines offered for sale are set by gasoline refiners and marketers based on their perception of the technical and competitive needs in the market. Federal and most state regulations do not regulate minimum octane values, only that the postings on the dispensers accurately reflect the octane number of the gasolines being sold.
Gasoline with a higher heating value (energy content) provides better fuel economy. Traditionally, premium gasoline has had a slightly higher heating value than regular, and, thus, provides slightly better fuel economy, but it is difficult to detect in normal driving. There can be even larger differences in heating value between batches of gasoline from the same refinery, between summer and winter volatility classes, or between brands of gasoline from different refineries because of compositional differences. The differences are small and there is no practical way for the consumer to identify gasoline with a higher-than-average heating value.
