A few years ago I had an 86 model diesel Hilux and found that the quality of different companys fuels varied enough to effect the performance an amazing amount, I have just bought a crdi Terracan after years of driving an LPG Patrol, does anybody find the quality still varies and who's fuel is best to use?

thanks

Having a CRD too for a couple of years now, I've been surprised to find that I've not really suffered because of bad fuel anywhere I've filled up from. I tend to try and buy from large name-brand (Shell, Mobil, etc) truck stops and only on occaision have had to fill up at little country town pumps. The motor has always handled the unknown juice well, and I put that down to highly-computerised engine management being able to compensate for bad quality to a degree. I've checked my water trap a couple of times to find it empty - so I've been lucky enough to be able to avoid the dodgy fuel thus far.

Hi There bozo, I only fill up at the BP now. I have 89 2.8 diesel d/cab toyota and noticed a difference between fuels. Not a major diff but seems to start better unless it's just my imagination, and to be less smoke when first firing up. I should also warn people if reading this forum and live in the western suburbs of blacktown NSW don't fill up at the mobil on the corner of buggarbee rd and blacktown rd as they have had bad fuel lately resulting in one lady that I know of having to replace the pump on her 04 turbo hilux. The fuel was like mud it's now costing her $3500.00 to have a new pump until she can prove the bad batch of fuel. Toyota have confirmed that it was the fuel as sample's were taken. Be wary Take Care Vitara

Hi there wallypop, I must say that's pretty keen every 5k for filter I imagine they would be quit expensive. I am very fussy with oil filter I used to change it every 2 n a half k now I am in the process of running it to 4 K just to see how the oil is. I asked the question on here a while ago and was told every 5k should be ok so I thought I would add extra 500k each time so I can keep an eye on the viscousity of the oil. I'm a bit slack with my fuel filter I must say, I just changed it 2 weeks ago 25k interval not sure if that is to long or not Maybe I was lucky didn't have any probs and there was no water in the trap.

Why not cut your old filter open and see what the guts looks like? You may find that there is minimal evidence of any crap build up. That is how I have been able to establish that my DeBug unit is working well; my CAV filters stay very clean, even after 20,000klms

I use BP whenever I can (here in Kadina I can use my Woolies discount voucher to get 4 cents off, even though there is a Woolies garage only 200 meters away).

I also believe in the merits of the Morison DeBug unit I have fitted before the CAV filter which I've used to replace the OE filter. The Morison's unit is a simple alloy bowl with 3 large magnets in it.....any sand, grit or algae don't get past it. When I do change my CAV unit after about every 20,000klms, it is always very clean and I find i could have left it there even longer.

Truckies have the right idea.....they fill-up their diesel tank/s in the early morning when it's the coolest time of the day.
Also, if you know that a tanker has just delivered fuel to the servo, don't fill-up; cos dumping a few thousand litres into the tank tends to stir up all the crud on the bottom of the tank and it ends up in YOUR tank. I realise this is a bit difficult to monitor of course.

I always found that BP was the best (most consistant and made the best power) and Caltex was very average. I used the Hilux to tow my racecar up the highway and the Caltex fuel quite often stopped me going over 80kph. With BP I could sit on 110, bit embarasing when the racecar had Caltex down both sides!

Now that low sulfur diesel has come in there are only a handfull of refineries producing it so it is probably all the same. When I worked for the BP distributor in Alice a few years ago BP, Mobil, Caltex and Woolies were all getting their diesel out of the Mobil refinery in Adelaide (I believe this has since changed, don't know if that refinery still operates). Diesel in Darwin was coming out of Singapore regardless of retailer. Storage will be the factor affecting fuel quality and this will vary from site to site regardless of retailer.
