and so do I, this fuel we are dealing with today is really something. This will all come together in the end so bear with me. I run a small engine repair shop and in all my years I've never seen so many fuel problems as now. It seems almost impossible but how can you take a vehicle that has a plastic fuel tank, rubber fuel line, alluminum carb and have a layer of rusty sediment laying in the carb bowl plugging the jets ?!!!! this isn't an isolated incident .....we deal with it all day. I attended a Briggs & Stratton service school and in a discussion on fuel quality (or lack there of) we were told Briggs has detrmined with testing that a 5 gal. jug of fuel...if left alone on your garage floor for 30 days will lose 4-7 points in octane !! as well as "settle" . I've seen see thru fuel filters that look clean but gas barely trickles through them, I've seen engines that won't start with the fuel in the tank....but if you prime them with "fresh" fuel at the spark plug they will run, untill tomorrow.

I have a good friend who owns a gas station, and for years he has changed the filters on the pumps once a month, now as reccommended by the fuel company he has to use a more expensive filter ( almost $80.00) and change them weekly...to protect the pump from damage.
So to any skeptics out there, IMO , as we have been saying it's never been more important to use good quality HIGH octane fuel in our Rovers AND from my experience I would reccommend changing the fuel filters way more often than the traditional intervals.

 

http://www.autopartsgiant.com has the Bosch fuel filter for $15. It will cost $30+ at the dealer. same part will fit D1 and D2.

here is a write up on how to change the filter.

There is NO fuel filter on a DII, only DI's have them.
I change mine once a year.
I have been telling people for years that gas goes stale in under 30 days and that if you plan on storing gas for longer than that to treat it with fuel stabilizer.
I treat my lawn mower gas as well as run it dry before winter storage, then fresh gas in the spring, fires right up first or second pull each and every time, same thing with the snowblower and chainsaw.

And if I am at a unfamiliar gas station with my truck, I buy 87 octane gas. I made the mistake of buying premium at a small town gas station on a off roading trip, truck ran like crap because the gas was stale in the ground.
Lesson learned.

You get what you pay for, buy gas at Sam's club every week and then wonder why your truck runs like crap and starts hard when cold.

I always get to laugh at my neighbor, 36" of fresh snowfall and he is shoveling because his snowblower wont start.
3 primes, full choke and one yank on the rope and mine fires right up each and every time.
I also "exercise" my snowblower once a week if it has not snowed.

 

That write up is over kill, just loosen the filter, let the cup of fuel drain and then remove the filter.
Replace new filter and start the engine, it will stall, restart and you are done.
It is a good idea to coat the filter threads with anti-seize to prevent them from rusting.

 

There are several new Stabil brand products available now that address the ethanol issue, as well as some "snake oil " on the market too. Probably best to stick with what you know.
and.... I too highly reccommend that you add a fuel stabilizer to anything that's going to sit for more than 2 or 3 weeks between use

 

I'm going to install a methane injection system to help offset the poor fuel quality. Going to run a hose directly from the driver seat to the intake manifold.

 

You could power your truck on pure methane if you did that.

 

I'd be afraid of a backfire !

 

Good point. The smell of singed hair would never come out of the truck.

 

I had to get the carb on my mower rebuilt and the guy at the shop told me to use premium unleaded because of all the crap in regular gas. May cost more but I use less to cut the lawn. He also said that when using mixed gas for the weed trimmer to use 1 bottle to 3/4 gallon instead of 1 to 1 because he has seen a lot of those burned up.

Also, I found a station that sells 100% gas, no ethanol. I've noticed that I get an extra 2mpg. Only catch is that it idles higher (900rpm).
