I was thinking tonight, and Im not even sure this is where I need to post this but here it goes.

Low sulfur diesel isn't going to help our pumps any, its only going to make them worse. ATF seems to be a fairly good lubricant, and I was wondering about everyone's input on long term atf use. I was thinking about putting some in with every tank. Or is there another additive people feel is better and should be used?

The diesel fuel they sell today isn't anything like what it used to be. Its wearing our pumps out quicker than ever. Im just thinking for the other drivers here who drive vehicles with 200k+ on them, and how to preserve our fuel system as long as we can.

What are your thoughts on this acticle Coke?

Its interesting, to say the least. Explains some things anyways. But minimum lubricity level is not enough for me. My pump has 263k miles on it, and i'd like to think it would last at least another 50-100k. Im not overly concerned with seal failure, my seals haven't leaked yet and i've been using the low sulfur diesel, 500ppm maybe, for a couple months now. The biggest thing im concerned about is the lubricity. My pump works better and the car runs better when I thicken the fuel, using either ATF or parafin wax.

My solution to the decreased lubricity of ULSD is to use biodiesel - as an additive or straight B100. One reason for the mandated switch to B5 (5% biodiesel) in all diesel fuel by 2010 is the improved lubricity of the biodiesel. So far B100 is no more expensive than petrodiesel in the GTA thus cheaper than any additive. B5 is sufficient for lubricity.
And there are more advantages to biodiesel as well - cleaner fuel system due to cleaning properties, higher cetane value, cleaner burning, carbon neutral, non-toxic, biodegradeable.

I've been throwing a couple of ounces of 2-stroke oil in at every fillup. It's cheap and it probably does the trick. Or maybe not. Eh, I figured it's worth a shot.

philav8r, where in the GTA is B100 available? Thanks.

if you arent concerned with seal failure, you will when your pump starts pee-ing all over your driveway :lol: (i now park on the road)

i'm just gonna keep driving my car the way it is (doesn't seem to be doing too much damage to my pump...)

after fixing oil/coolant mixing problems, and needing my injectors rebuilt, fixing a leaky pump isn't my concern at the moment (i do use diesel lubricant though!)

B100 is (has/been?) available at Trucktown Terminals s.side Steeles Ave. just east of James Snow Parkway. They told me that the B100 would probably be available until October when they expect it to be too cold. They wil have B20 year round.

Apparently models built after 1996 are resistant to biodiesel i.e. the seals and lines are biodiesel resistant.

I had heard it happened in 1993 when the sulpher % dropped down to 500 (or whatever the number is)

those bastards... nevermind mentioning that the new diesel fuel might make your car leak... (1 litre of diesel can contaminate hundreds of thousands of litres of water... which is worse for the environment??!!!)

burn_your_money · « **Reply #11 on:** September 26, 2006, 08:57:47 am »

jtanguay are you comparing the old diesel to the new stuff, or diesel to biodiesel?

jtanguay · « **Reply #12 on:** September 27, 2006, 02:10:32 pm »

I'm definitely comparing big dirty diesel

What I'm wondering, is if I get my pump rebuilt by say.. Giles... will it be biodiesel ready? (I assume he would use the new style seals)

Other than the fact that I would need to change a few fuel lines of course...

If I go that route (which I'm currently saving to do...) I might as well drive with biodiesel. I do like the black smoke though... :twisted:

The new ULSD will have a diferent additive to lubricate. Still the same trucks going to the same tanks and pumping in the additive for the station they deliver to. No need to change anything. Seals may have issues with the new additive but there will be seal additives too. Remember when we were going to lose charcoal lighter fluid? Now we don't even think about it. BBQ are still happening and we move on.

The ULSD is better. Comparing the motors of the 80's to today (in the USA), there is 6 times the pollutants. with ULSD this is changed to almost 60 times the pollutants. If you car leaks fix it. Seals are not that expensive. The biggest difference is the cleaner burning trucks, locomotives and ships. A lot of info is available on the gas companies web sites. Some even tell what their additive will be.

I got USLD (15 ppm) today. I noticed the smell of the fuel at my local station smelled different, and the fuel actually felt like it was more like fuel oil than skinny fuels. However, my local station still lists it at 500 ppm, maybe its 15 and they haven't updated the sticker..
