2) What about the additives that are added already at the gas station?
The reason why I ask it a buddy of mine said he used it in his truck and it ate away the seals and gaskets.
Suggestions would help as it was 67 yesterday for the high and it will be in the 20's for the low in a few days.
--------------------------------------------------
There were two periods when diesel fuel caused the seals and gaskets to leak. I copied the following explanation from a Chevron Website titled:
Fuel Leaks From Seals of Vehicles Using Ultra Low Sulfur Diesel starting in 2006:
Some vehicle owners, who recently began using the new EPA regulated ultra low sulfur (S15) diesel fuel, report that their vehicles have developed fuel leaks. Similar occurrences were reported in the early 1990’s when low sulfur fuel (S500) was introduced. The leaks in the 1990’s occured at points where elastomers (Orings) are used to seal joints in the fuel system. During the 1993-94 period, the most common occurrences were injector fuel pump leaks.
This problem is not exclusive to one engine type, one fuel type, or one geographic region. It can affect some engines that are older than ten years, but some newer ones have experienced the problem as well. The reoccurrence of these fuel leaks could become widespread geographically when the majority of fuel supplies are switched to S15. However, it is anticipated that only a very small fraction of the vehicles may be affected.
Should further elastomer failures occur, they are expected to be sporadic. Seals in some vehicles may fail while similar seals in other vehicles using the same fuel may not. Past experience indicates that the common denominator is expected to be nitrile rubber (Buna N)
seals that have seen long service at high temperatures. High temperatures have a tendency to accelerate seal aging. The reduction in sulfur content is not responsible for the problem.
Two explanations have been offered to explain the sudden occurrence of seal failures:
•Many of the new S15 fuels are expected to contain lower levels of aromatics. The change from a higher to a lower aromatics fuel can cause seals to shrink. Aged seals, which do not have the elasticity to adapt to this change, appear to fail sooner.
•Some of the new S15 fuels are expected to be more susceptible to oxidation. The resulting oxidation products (peroxides) could attack the seal material and cause it to prematurely age.
I have many pdf files regarding this same problem.
Take care,
