Fuel Econmony Hit in Winter

quote="allan5oh"]Yes, but it does not measure the a/f ratio. When I mean feedback, I mean strictly a/f ratio.

agreed, when we discuss open loop, it would be assumed that we're talking about a fuel trim loop that is ignoring the o2 sensor (engine warm-up). i'm pretty certain that '07 engines do not measure exhaust gas content either

You're right, the new engines need to be run very precisely regarding a/f ratios. Too rich and PMs increase, too lean NOx increases. That's why cat uses variable valve timing, and all others use a variable geometry turbo.[/quote

The only trucks I have seen running #2 diesel in Manitoba in the winter time are the one's sitting froze up alongside the road.

If you're fuelling in Manitoba after Sept 15 of the year you're running number 1 anyhow.

Most Canadian truckdrivers know better than to try to run #2 diesel in the wintertime.

Same up here except normally they mix 1&2

And most drivers from Manitoba will tell you when their truck freezes up it's from "fuel gelling". Right.

My truck has never been on the side of the road.

When I fuel up #2, it's in the states.

Proper maintenance (and monitoring excess WATER in your system) go a long way.

straight #2 won't get as far north as i am. if it does, it willl freeze on the way, following shut-down, or while idling. BTDT, got the shirt and the pics... flows like butter in current ambient temps... i'm thinking manitoba should have a bigger problem than here

in my area, there is also no option for buying #1, #2, or blended fuel... you buy diesel and the distributors determine when they will blend #1 into the #2 to lower cloud point... never seems to be an issue.

never encountered anyone in OTR that runs straight #1 but, i do know of the adverse effects of #1 in our local transit garage =(

[/quote]It is also a good idea to drain any water accumulation you may get in your tanks occaisionally...less chance for it to be picked up into the fuel stream AND, there are little microorganisms which lieterally EAT diesel fuel but reside in the water and the fuel/water barrier. Their excrement resembles snotty bogies...and can gum up a filter real quick. So if you get your fuel from a joint that is "infected", if you will, your tanks can now be "infected" as well. There are bio-inhibitors out there that you add (just like anti-gel) to prevent or correct this.[/quote]


We used to use a diesel fuel conditioner that put a stop to the micro-organisims made all the difference in the world.
