I remember reading somewhere on the BOK that you can use transmission fluid as an additive to your fuel to clean the injectors. I tried searching for this with no luck. If I remember correctly, it is cheaper then diesel additives and actually works better. I just wanted to confirm that you can add it before I go dumping it in. If it is recommended, how much per tank?
Thanks

Me, I wouldn't. It's on old dieseller's trick, but with the more modern pumps and indeed more modern ATF the situation is different.

The pump requires as much lubricity (lubrication, slipperyness) as it can, but ATF contains "friction modifiers" to make the clutches in the tranny grip tighter. Bit of a conflict there, then.

A better alternative if it's local to you is a couple of litres of biodiesel per tank of dino. You'll get all the benefits of bio or indeed a fuel treatment at as low as 5% biod

Skews for being thick but what exactly is 'bio-diesel'.

Chinese have a new technology to make commercial diesel from old tyres, or so I've been told.

... and the French are going to make fuel from surplus wine?

Please don't crucify me but I'm considering removing all the 4WD gear to make our MasterAce Surf 2.0 TD a 2WD to save weight. We use the bus alot and I'm keen to get more mpg. (I've removed the ECR)We don't do off road much. ?is it worth doing (from the weight perspective) and roughly how would I go about it. Ideas welcome.

Rob - always start a new thread for a new topic. It gets you more visibility and helps Dave Mason to archive properly.

You are talking a lot of work for little gain in removing the 4WD. The suspension and steering knuckle asemblies are different, there's the 4WD diff, transmission and driveshafts to remove and then there's the extra horizontal rad and plumbing to consider. Plus probably other things I haven't even thought about. And for what a possible 10 mpg if you are lucky? I wouldn't entertain it. I consider the 4WD a bonus. If you really want a 2WD, trade it in for the 2WD model.

I personally don't think it's the weight that reduces the mpgs in a 4x4. The final drive ratios differ (4.556:1 in a 4x4 auto vs 4.1:1 in the 2wd), plus the gubbins inside the transfer box (oil pump etc) add drag. Nothing at the front adds drag when in 2wd mode, and the weight difference between 2wd and 4x4 is likely only the same as having a couple of bodies in the back seat...

If it were me, and I *really* wanted to do something about it, I'd swap the rear end and possibly gut the transfer box- if so desired you could do both damn near in-situ. You'd need to sort the speedo to match the diff tho.
