But let's just use what I said as a relative reference, most of these fuel additives are probably disolved in a mixture of solvents that are a similar density and probably also similar to gasoline, so assuming you add 1oz of techron concentrate which is ~30% PEA by weight in a gallon of gas that means that. It's what shows up in the wiki article, but I can't locate the orginal source that is cited on the wiki. I'm know I'm being a bit over analytical considering 100ppm v 400ppm and the unknown as to what the PEA level in Techron is. I'm trying to get reasonably close to Chevron gas level. I add some Techron when fueling with non Chevron gas. Https:/ / forums/ ubbthreads.php/ topics/ 5166791/ 9 IWhere did you learn this? From this thread (sorry I couldn't link the exact post) Chevron is 100ppm of their additive pack which I assume is primarily PEA. Although there is one potential issue with my math i believe the MSDS gives concentration by weight, and the products are sold by fluid oz, so technically if the density of the carrier solvents used in the products is of a majorly varying densities the stuff I said about how much pure PEA the product has might not be a useful figure. a 20oz bottle of techron has about 6oz of PEA in it, when compared to gumout Regaine products which seem to average around 1.2-1.8oz per bottle, that means that they put about 800ppm to 1200ppm of PEA in a 20gallon tank. 75oz per gallon so that'd be about 3000ppm. Maintenance dose would refer to an amount added to every tank of fuel to help maintain keeping parts clean, Redline used to recomment something like 1/6th oz per gallon which would be close to 600ppm, Redline's new instruction is to add 1 15oz bottle every 1500mi to upto 20gal of fuel to perform a complete fuel system cleaning, Since the Redline seems to have about the same concentration of PEA as Techron when you use 1oz per gallon in the case of a 15 gallon fuel tank that should be around 4000ppm in the tank when added to 20 gallons that's about. So, i guess what is the equivalent treat rate for each to achieve that.i'm a bit busy now, but will calculate later unless someone wants to beat me to it. On the topic of maintenance dose, its not really clear what anyone is actually recommending which was my original point.īut I do think the concentration should be 10x the typical top tier dose to do anything (~4000ppm). Anymore I don't think maintenance dosages really mean anything if you use top tier gas since I assume that the newer top tier gas has a lot more detergent than fuel did back in the early 2000s when Pedline used to recommend a maintenance doseage, plus most cars are GDI now and you don't get the intake valve cleaning action since the fuel doesn't contact the back of the valves although running a large dose every 1500-3000mi as recommended by most fuel additive manufacturers should help keep the injectors clean and may help reduce build up on O2 sensors and catalytic converters.Īnymore I don't think maintenance dosages really mean anything if you use top tier gas since I assume that the newer top tier gas has a lot more detergent than fuel did back in the early 2000s when Pedline used to recommend a maintenance doseage, plus most cars are GDI now and you don't get the intake valve cleaning action since the fuel doesn't contact the back of the valves although running a large dose every 1500-3000mi as recommended by most fuel additive manufacturers should help keep the injectors clean and may help reduce build up on O2 sensors and catalytic converters.įirst of all thanks for that information in general. The old whitepaper for SI mentioned using 15oz per 100gal as a maintenance dose, so around 1.5oz per 10gal, so if we consider that the concentration of PEA is roughly equal to Techron which when used at 1oz/gallon leaves a concentration of ~4000ppm of PEA so using 0.15oz/gallon would leave a concetration of like 600ppm which is about 1.5x what you'd expect to find in top tier gas. Redline recommends using one 15oz bottle to treat upto 20oz when used as an immediate fuel system cleaner. Redline SI-1 has about the same concentration as Techron. The Gumout high mileage fuel system cleaner with regaine says something like 20-30% PEA on it so in a 6oz bottle there's like 1.2-1.8oz of PEA. The only gumout product I have any idea on pea content is the multi system tune up where the SDS specifies there is 5-10% pea but ays that there are 9.63% of the composition is of unknown toxicity which leaves me to believe there is around 1.5oz of PEA. If it helps, Chevron gas is said to have about 400ppm of PEA (Techron) in it, they say the complete fuel system cleaner is about 10x that concentration so about 4000ppm when used in at the recommended dose.
