just buy premium fuel. Shell V power, BP Utimate etc. Job done.

I tend to run one full tank a month of the 'good stuff' from a BP, Shell, Esso etc. ‘brand name fuel station' but after that just run the normal suff from the same ‘brand name’ stations ... I try to give the supermarkets a miss if possible nowadays. Poppy - TDCI (Puma) 110XS 2.2 - Camper conversion - see the build here - https://www.defender2.net/forum/topic56530.html

Premium fuel every time for me....
I did use to run a cetane booster at times, i have a hybrid turbo setup but after i ran out last time i never got around to ordering more... Maybe i will now that you've jolted my memory 
https://www.millersoils-shop.co.uk/diesel-power-ecomax tend to use shell just because it's the closest Use it on all the modern cars and they seem to run much better on it, well worth the premium, on the old oil burner series car's just standard but the modern stuff is all premium |

^^^^ This - although Opie Oils is, I think* cheaper than that price and the club discount code is 'DEF2'.
I use the Millers all the time, I find it easier to use and premium Diesel isn't available everywhere. You can use one or the other but not both, so premium diesel, or standard diesel with additive. I use the latter. (Bottles come with dosing measure, easy as pie to do.)  |

As above : Millers from Opie Oils, a site sponsor. Cheaper than premium diesel and seems to work. Of course no real evidence that it works, but keeps me happy

Thanks all for that. Was thinking of every other tank put a premium in, n normal good quality diesel in otherwise. 2020 First Ed 110.
replaced by 2021 250 110 Commercial Defender_uk |

I wouldn't vary Cetane levels by switching, the ECM adjusts to various fuel qualities I believe.
(Not proclaiming to be an expert just suggesting my current knowledge). So if you keep swapping the fuelling calibration will keep on adjusting, not constantly but every few start cycles. I think you'll find you won't get maximum best effect, and performance by varying. When I started using the additive I could hardly tell the difference except slightly more power and smoother. If you stop using it suddenly and go back to standard diesel I definitely can tell the difference and don't like it. It doesn't cost much at all and goes a long way.. LR when designing the Defender took into account worldwide fuel quality, which is why performance can be quite low from the factory. For example some fuel supplies in remote Aus can be fairly poor, here in the UK we have relatively high quality fuels. So we can easily have a tune to improve performance as standard, making best use and performance and efficiency from the fuels we have. I've been running the Millers for a couple of years now, every day. Personal choice, the choice is yours. |

Interested to know more about this if anyone has the knowledge? Solved the bowel problem, working on the consonants... |

A bit beyond my scope, but most of the tuners are aware of such details.

It’s a good point though to use the same fuel consistently
another question for me to ask the lads at Stonelake |

In a pre ECM vehicle with no live ECU fuelling characteristics performance will just depend purely on the fuel being used.
It will simply be varied depending on the fuel taken up to the carb, and perform acordingly to that. The Puma's ECM adjusts fuelling and injector pressures etc of electronic performance parameters dependant on the fuel. Really, to give the best, smoothest most economical performance. For example, I'd imagine a petrol supercar would be manufacturer recommended to run on premium 'super' petrol? Can anyone confirm that? In the Puma at least, you will do no harm if you run standard or premium diesel or as I do standard diesel with additive. (Effectively making it premium diesel with additives due to increased Cetane rating etc.) It will however affect performance, and it isn't a placebo in my view at all. This is why I wouldn't recommend switching regularly, if you have no choice or you can't for what ever reason you won't ever do any harm. But you will not achieve the best permanent performance on-going. I would definitely stay on one or the other side of the fence only. You can add a little more additive so it says on the bottle, but I would and don't as a rule. Not to permanently run on and I also wouldn't use premium diesel AND the additive. This being said, I've never used premium diesel purely due to accessibility reasons. But I am more than happy with my pretty much permanent esso standard to Millers mix, rarely shell standard if I had to. If I go further afield and need more fuel, I tend to take my 20L Jerry can anyway, and again fill all at once and gives me a good bear 300 or so mile range on one fuel station visit. (Estimated range here I hasten to add.) Some may say a little obsessive but as far as I'm concerned my 90 is running like a dream on this method. Same premium brand fuel supplier, same additive, accurate dosing = perfect top performance. Capped off by Gary @ Alice's excellent tune, I'm very pleased indeed! |

To be precise 'Premium Unleaded' in the UK is just our normal unleaded, Super Unleaded is the more expensive stuff and in the US for example they also have a cheaper poorer petrol available too. Most performance cars specify 'premium unleaded', which just means the normal UK stuff. If an engine has a knock sensor (I've not checked if the puma has), then the ECU will adjust the timing until just before it starts to knock. As super unleaded is a higher octane it will allow more timing advance before it starts to knock. So with super unleaded the ECU will advance the timing further giving more power. The Cetane rating on diesel fuels has a similar effect. If you swap to a lower grade fuel, then it will knock more so the engine will retard the timing and reduce performance to match the fuel. So I don't see any point swapping from one to the other periodically other than to 'feel the difference'. On an old carb engine it would just run at what ever you'd set the mixture and timing too. So putting in higher octane fuel would make little or no difference, unless you went and adjusted the timing and mixture to take advantage of it. There was no computer to do this for you. |
