The failure occurs when seals that were swollen because of the aromatics in the NON-ULSD now shrink when those aromatics are removed in the new ULSD fuel. If your 'new' lift pump wasn't exposed to the old diesel fuel, the seals should not swell/shrink and you should no longer have the leak problem with the lift pump.
The real question for you at this point after replacing the lift pump is whether or not using 2 cycle oil will expose the lift pump seals to 'stuff' that will again swell them and potentially start the swell/shrink cycle all over again for you - effectively negating the gain you just made by replacing the lift pump.

Thanks, Mike. Guess I'll just continue reading till I learn all you know before I make my decision. Figure carrying a few gallons of 2 cycle oil will just add weight I can't handle, also.

Does anyone know if all 2 cycle oil with the TC-W3 spec is ashless? Is there a TC-W3 spec 2 cycle oil that is not ashless? I saw Pennzoil TC-W3 spec that did not have the words "ashless" anywhere on the bottle. Thanks

Hi Larry and all the Country Coach Owner Folks, I find many of the questions posted can be answered with Googling - Ashless is one of them. But Ashless may not be the issue. What diesel engine fuel additive can be used to lubricate the gaskets is the issue.

The answers to most questions can be found in the CCI manuals. There are a few that need group help but many were answered in the first 5000 messages and here we are now over 30,000.
I'm not trying to single out anyone - just making an observation.
I enjoy this group.

Thanks Fred. Yes, I previously tried "Yahooing" "TCW3" and "ashless", but the answer didn't jump out at me. Maybe I need to look closer. I know what you mean about reading the CC manuals.
I have read them many times over and agree they are full of very useful information. I even spent the $200 to purchase them because they didn't come with my used coach. Happy trails...

I still have not found any reason to use ashless oil in fuel instead of standard lubricating oil. Forums can think of many illogical unproven reasons to use ashless oil & magazines can write of it without test results or engine manufacturer validation. Amsoil can sell it for much more than market price. But I still have no valid reason to add $17 per gallon oil to fuel instead of $7 per gallon oil.
Diesels burn oil. 2 stroke diesels usually burn bunker oil or minimally refined oil.

My new Poulan trimmer has a 50 hour rated engine life. My Cat is rated about 8000 hours engine life. It seems a flight of fancy to believe 2 stroke weed eater oil is what the Cat should drink.

Where can I see some information that supports ashless oil added to fuel as better than 10W30, based on long term engine life & fuel economy?

You raise some very familiar concerns about California regulations > regarding "pollution" rules.

I was in the aerospace paint industry, when back in the '70's and 80's, we "couldn't believe" the outrageous ideas they (California) were pushing in the name of environment. They ended up costing our industry and our customers millions of dollars and, in many cases, promoting the use of inferior performing coatings. The development and flight testing of the waterborne and high solids materials has taken years.

Brad, I think of environmental controls every time I see a piece of space shuttle insulation foam fall off as a result of the forced use of inferior adhesives.

I received an email coupon from Seven Feathers Resort and RV offering $10 in free fuel for each night one stays at either the hotel or RV resort. Since it is good for only January and February it does me no good here in Arizona. If you know you will be staying at Seven Feathers in Canyonville, Oregon in the next couple of months let me know and I will email you the coupon.
