How much do you TDCI owners notice the difference between Diesel from different servos? I'm refraining from saying different brands as I think the condition of a servos tanks and how busy it is (how fresh the fuel is) can be contributing factors as well.
The reason I ask is that I have experienced marked differences in performance over the last few tanks. Enough to really take notice of. On my previous tank which was Caltex Vortex from a large busy servo I noticed how much better it was going over the previous tank which was from a Shell. Then I filled up the other day at a 7-11 and it is running noticeably worse (than the Shell even). I have to give it a much bigger prod to get it moving and it will kick down when accelerating on the motorway when it would have done it in 6th before with ease. Just wondering if you have experience similar differences?

Hi Binny,
I have a MB Zetec and notice a marked difference between Caltex Vortex and BP Ultimate Diesel. Goes alright on the Vortex and when running on BP Ultimate Diesel is a definite improvement in both consumption and engine running. Quote:

Thanks for your feedback.
Your varied experiences align with my theory that its not necessarily the brand that make the difference. It can also be the particular servo and the condition of their tanks, age of the fuel etc. I'll go back to the Caltex next tank and see if it comes good again. Problem is it goes so far on a tank lol. Even my transmission seems confused at the moment due to the decrease in torque. It feels like its lost 50Nm.

I know its an old thread but I have had first hand experience with poor quailty diesel. We have a CRD Jeep and like many others tried to fill up at the cheapest price and with the occasional tank of biodiesel (freedom fuels sell a 5% blend). One day I noticed a slight diesel smell coming from the front of the car and noticed a small wet spot underneath. I booked it in for a service a few weeks later and found out that the high sulfur content that was in the cheaper/bio diesels had eaten away at the seals, injectors and fuel pump! Complete strip down of the motor, new seals, fuel pump, system flush and injectors (8K later) shes running better then new.
The diesel mechanic who did the work told me that BP is currently the only company that certify their own fuel internationally once refined. Not sure if things have changed as this was a few years ago but have only used shell a handful of times since and there is a noticeable performance and km distance for sure. |

mine feels sluggish and smokes like a mofo on BP diesel, yet is clean and perky on Caltex or Woolworths express premium diesel. I prefer to go to Caltex as it has a Pay at the pump system and I love that option.

well 7-11 fuel because its mobil..
placebo effect, power, fuel usage. the reality is I cant tell the difference with diesel, not in a way my petrol V8 hence the mobil.. so I go for the best turn over, for low risk with water contaminates.

That's why I said earlier that there could be other factors at play besides the brand. I think it can vary a lot between servos based on quality and age of the tanks and how busy the servo is. The more turnover they have the less chance fuel is old.
FWIW since I last posted here in March I have used only BP ultimate or Caltex Vortex diesel from the same servos every time. It has run consistently well since then. I can guarantee it's not a placebo effect. The difference was too great. It ran so bad on 7/11 "special" Diesel that I thought there was something wrong with the car.

I only put BP and Shell diesel in my new Mazda 6 TD and don't notice a difference at all to be honest. Havent tried others as the only places I fill up are these 2 brands (BP round the corner at home and Shell near work)...
