That "Fuel Chart" has no real legitimacy I've tried contacting the people who created that chart, or tried finding them in general with no luck. The chart uses diesel fuel that is not sold at the pump.
Maryn International Ltd, or PowerUp Lubricants has done a REAL study and you can call them and they will confirm it. They make a product called GEN 49D. They used Diesel Fuel from Shell that had an HFRR (how well it lubricate, lower the number better it lubricates) rating of 508. 520 is Fed standard. Then they tested it with Power Service Diesel Kleen. The HFRR was brought down to 388, now thats really good. They also tested the fuel with other additives including Howes. Howes Diesel Treat+Anti Gel brought it to 386, ok thats good. Keep in mind they tested the fuel with lots of other additives.
Howes Meaner power cleaner got a 362 HFRR rating, then Power Service Fuel Supplement got a really good 334 HFRR rating. Thats way better than 2 cycle and Howes.
According to The Other chart from Diesel Page 2 Cycle got a 474 HFRR rating.
Then PowerUps GEN 49D got a super low 296 HFRR rating.
The point is, the Study from the Diesel Page can not be confirmed as real. People PRAISE that chart, but wheres the evidence of its neutralness, and legitimacy . The chart from MARYN/PowerUp is real and you can call the President of Sales and Marketing and He will confirm their chart. How do I know, because I called them to verify the legitimacy of their chart. They did a real study and scientific research for their chart. Unlike the PRAISED ALL MIGHTY diesel page chart. Which used LAB based Diesel fuel rated at 636 HFRR, which is not sold at the pumps. So its not a realistic fuel to test with.
Do research, don't follow the hype. I would stay with a product that is made to BLEND with ULSD fuels and not something made for gasoline.
By and By Maryn is out of Canada, and PowerUp lubricants are out of Texas. Its the same company.
Oh and the stuff in PowerService helps clean as well as lubricate. The Pee-tree dish test is not valid.
Sorry if I sound angry, just tired of people believing in hype and what they "hear" vs doing alittle research.
After talking with Jerry from PowerUp he said if 2 cycle was a great product for DIESEL fuel they would sell it and advertise it as a DIESEL FUEL LUBRICANT, but its not, its made for GASOLINE, he said it does lubricate, thats not the debate. But its not made for diesel fuel. He recommended buying a product that is made for ULSD fuels. And offered me to try their GEN 49D. I may, but its easier to find PowerService.
The other chart from the Diesel Page is out there was a study, but don't let that be your only source of information. Some companies I've talk to think that the chart is made to make Opti Lube look the best. And some companies were approached to do a study and if they "donated" $3000 then they will be used. Yet Power Service and I think Lucas had declined to be involved, yet some how their products still got into the study. Strange Huh!
