Fuel treatments for diesels.

[Wilko76]

Hey

The old man dropped around some fuel treatment he grabbed from a crowd in Wacol called CEM. I know they also do an engine flush also.

How do you guys rate fuel treatments ie injector cleaner? Are they worth the price?

[Turbz]

I have never used them so I cant say. That engine flush crap works a treat but. Smokes your engine to peices but engine flush crap is good stuff.

Their over-rated at best IMO/ I used chemtech diesel power for a while, notice about 20 extra k's per tank. Not really worht it at $30 a bottle

[tweak'e]

i run some every know and then. mainly for the anti fungal in it but it also helps keeps the tanks etc a bit cleaner and motor seems to run a bit better on it. however some fuel additives make it run slower so be carefull on wha you use.

i think the current one is cemtech (i;ll have to check).

It may be $30 a bottle, but you use bugger all of it.

1L bottle, with minimum dosage of 10mL per 40L of fuel (as per directions) gives you 100 tank treatments.

100 tanks, and 20km extra per tank equals 2000kms extra coz of that little bottle.

Work it out at 15L/100km... Thats a saving of 300L. At 125.9cpl, thats a saving of $378. Overall, a $348 saving minus the cost of the bottle.

Even if you double the dosage rate, you're still saving money.

OK, I've done my maths for today

I also use Chemtech, and I find it to work quite well. My bro-in-law was having troubles with algae crap and water in his tank, blocking his filters... He dosed it with Chemtech Diesel power and hasn't had an issue since.

Ive tried most of them and it seemed a waste of money, but after reading reports on Chemtech, here on OL, I thought I would give that one a try.

I live in an area which is ALWAYS damp and I thought the fuel tank may have a build up of crap in it due to the dampness. Chemtech fixed the problem. The car is running better and my economy has gone up.

Rocky -- $30-00 a bottle ?????? What size bottle ? I pay $13-00.

What does a new or recon Rotary pump cost $$$$$$$$$$$$$

If the additive has an aditional lube for the cam then you are in front. New diesel has supposedly less lubricating properties.

I also use chemtech, best value for money on the market and does help treat algae.

One word of warning though that a Diesel specialist told me, do not use it continually, once every 10-20,000 kms is fine. What happens is that yes it cleans everything and helps remove water and crap but that water (because it is dissolved in the diesel) goes through your filter and through your pump. This is fine when pump is hot but when the pump cools the water comes out of suspension and provides an opportunity for rust to form on all the nice shiney parts inside the pump..... Not healthy Jan.

Now this guy could be pulling my leg, but I do trust him as he is also a friend.

One Litre bottle is around $30 at most car shops.

How does it corrode in an oily oxygen starved enviroment ?

[Wilko76]

all good points. this chemtech. where do you get it from?

Thats interesting Stinger, on not using it too much, because when I went to the Auto Shop to buy it ( I know the attendant personally) she said that Chemtech is what the Truckies buy, only in 5 litre containers. She says they swear by it.
I will go to my Diesel Mechanic and ask him.

And with the water : It may only be coincdence, but when I started using it (the same time I moved to the very damp area where my 4by is) I noticed the water filter always had a lot of water in it ???

Chemtech different to CEM? I used CEM oil treatment/ flush in an excavator that was billowing out white clouds of smoke and no power... result was it stopped smoking completely and full power. So it was worth the $120 then- it did save pulling the motor down.

Water has oxygen in it.
Same way bearings and gears rust in a diff with oil on top of water.

oxygen + hydrogen=water

[tweak'e]

water and even some oils will disolve oxygen into it. some of the treatments change the suface tension and breaks up the water into smaller bubbles which makes it easier to mix with deisel (not dissovled). hopefully it gets caught in the filter otherwise its pumped into the motor. you would have to have a serious water problem for it to seperate out in the pump.

What filter would you recommend, if it is letting more water through ?

[tweak'e]

if you have got water problems then you couldfit a dedicated water filter like a marine one. use the standard filter as well as the water one. tho i would be inclined to see why your getting a lot of water in the fuel. do you go a different gas station?

A marine filter ?????? I havnt heard of using one of those. What are the pro`s and con`s ??

I pretty much go to the same Servo. This particular Servo gets a lot of use -- Log Trucks , etc. On the very odd occasion I go to other Servo`s.
My 4by sits in the driveway in, as I said in a very damp area. I use my work car most of the time and thought the 4by might be getting a lot of condensation build up in the tank -- ????????

sorry marine is not quite accurate. you can get seperate water traps for trucks, tractors, boats (which is what made me think of it). a truck, marine shop would proberly have them on the shelf.
