Thread: Diesel that doesn't foam up

The only times i have noticed the diesel not foaming up was using bp regular diesel . The first time the auto shut off on the pump didn't work and i got fuel all over my boots . The disco seems to be running ok but i think the caltex diesel runs better.

Hey there Tombie,

Chill out dude. Like the old car ad disclaimer said "your mileage may vary".

I'm sorry to hear your experience was so bad.

I've had the opposite experience. Have generally always filled with BP (old habits from days when it was a company fuel card) and they were the only chain anywhere near me carrying Alpine Diesel during the winter months anyway. Brand loyalty I think the demographers call it.

While on a trip through the Flinders Ranges last October I filled up on other fuels a couple of times due to the lack of BP at the time.

Result: fuel consumption up, NVH up and power/torque down.

These are all mostly highway transit miles so not an unfair comparison.

Given my experience I'd class the other guys dino juice as ****.

It all boils down to a plethora of variables; from fuel sources, to engine tune, to air temperature/density and lots more, including personal preference. I tend to think the whole lot evens out in the end.

Your experience may not change my habits. Mine is unlikely to change yours. Are either of us unhappy with our everyday choices? I think not. Viva la difference. Without it there's no hope for us as a species.

Happy Rovering,
Iain

Not un-chilled.....

Always liked BP fuel and SA only just got this bio-rubbish blended stuff.

I agree one can get differing NVH from one batch or brand of fuel to another.

But the consumption change and obvious loss of power was very noticeable....

Topped up with local Shell product and within 5km was back to usual sound and power came back. (So did some NVH)

For what it’s worth.

I carry about 170Lt of fuel and use my 2001 TD5 as the daily comute into and out of Sydney.

I’ve every fuel receipt and kept complete records of fuel consumption since I purchased the Def.

I always go (trips excepted) to the same servo to fill up. Following another thread I switched servos and now go to Caltex and fill using their vortex (?) Did notice it foamed a bit when filling.

Switching to Caltex I immediately dropped fuel consumption by about ¾ L/100 power seemed improved (possible placebo) as did engine running. I now get under 10L/100 in Sydney driving. Not bad. (This improvement is over 6,319K’s).

Some years ago (had 200TDI Dico) I filled up at a “discount” fuel station a few times. It was directly opposite a Shell and was always 10c L cheaper than the Shell. I noticed a difference in power and consumption all bad. So stopped going.

About six months later I understand the station owner was charged with fuel dilution and was sued by a fleet owner for engine damage caused to his fleet of Volvo’s.

So I’m particular about the fuel that goes in and the oil I use. Now both Caltex.

(sorry if I drifted right off topic)

The answer to why BP Ultimate Diesel foams up less is due to the anti foaming ageant that is added, a long with the high performance injector cleaner, also it has the same sulphur level as ALL diesel sold in Australia, the legislated specification is 10ppm max. On any given day it will float between this, but never over 10ppm amd as low as 1ppm.
How do I know this? I work for BP.

The other comment on DPFs blocking is due to bio diesel, all vehicles sold in Australia now that have DPFs must be able to take up to 10ppm sulphur level,

I cant wait until BP Ultimate Diesel comes to Melbourne its a good product

There has been a few instances of engine damage, from fuel solidifying in the fuel lines and injector pumps, also when diesel that has contaminated oil in the sumps of tractors, solidifing during severe frosts, this has been due to the high amount of paraffin from the summer fuel used during the winter.


Timing the usage, then the topping up of farm storage tanks has been the answer to this problem, along with regular sump oil changes.

I've never heard of or experienced engine damage from waxed up diesel. It happens a lot here too.
It's just a major inconvenience when it's cold and nothing will start.

I can remember when.... diesel was honey coloured and oily to the touch. Jim

BP Fuel check
ust completed a fuel consumption check in the ute on a full load of BP dino diesel. Worked out at 9.23 litres/100km wandering around town, kids taxi etc. Not much above 80km/hr in traffic. Definitely foamed less on filling
checking a load of Caltex now.
