Diesel Additives

Now that I've upset everyone with my forthright views :angel:
Here's a set of pistons in a 300Tdi @ 325,000km. (we'll neglect the crack in #3 and the why's and wherefores at this stage)

They've seen a reasonably regular maintenance dose of Redline RL2, since around the 100,000km mark, just to keep things clean and reduce the necessity of a premature pump overhaul
The throttle spindle is starting to weep now and there's possibly a leak from the high pressure section of the pump, just haven't isolated it yet, although it could be tracking from the top of the pump. (spindle)

In another lifetime I regularly performed used oil analysis, Redline 85Plus and RL2 (I'm guessing they are the same product, just aimed at different markets) was the only diesel additive I tested at the time that didn't show elevated bearing wear metals, and that includes BP Dieselgo, BP's own proprietary diesel cleaner/lubricant.

As for the mineral vs synthetic two stroke oil argument, where the hell does that come from ? It doesn't make sense ?

Redlines diesel additives use a POE oil as a pump and cylinder lubricant.

Polyolester, one of the highest flash point synthetic base lubricants, the same base as they use in their racing two stroke oils, so why the constant harping on forums "only use mineral oils" ?

Don't believe anything you read online, including this post. :D

Do your own research.

I did read all the posts and I did not feign confusion. Thank you to those suggesting I'm either a cretinous moron or some form of stirrer.

Anyway at $15 bucks it can't hurt.

Yup! clean pipes are healthy pipes - my D2 gets Chemtech at the moment and I get Krill Oil :D each have their supporters and detractors.

I have found that the factor that most influences my (perceived) economy from each tank of fuel is how quickly I become bored with continuing to dribble fuel into the tank as froth makes its way up the filler neck.

If I get bored quickly, it makes the economy from the previous tank look good and makes the next one look bad.

On the other hand if I have nothing better to do and continue to dribble those last half dozen litres in, then the economy from the previous tank doesn't look as good, but it helps the next one from appearing to be particularly bad.

The next most significant factor is the slope on the service station driveway that affects how well I can fill the tank.

Headwinds make a big difference. Having two kayaks on top of the camper while driving into a headwind makes an even bigger difference.

The only factor that I have never noticed having any significant, real impact on economy is the brand of fuel I buy.

I remain very sceptical about most people's claims about variation in economy from miracle additives; especially those who express their fuel consumption as the number of kilometres travelled before they decide to top up the tank. :p:p:p

Over 86 fuel ups. Recon I'm acurate as I can be with speedo being out a bit and trusing fuel stations.
