  1. How much have they already invested in the engine plant at Wolverhampton? That's a lot to write off.
  2. Hardly surprising, given the boom in motorhome sales
  3. There's no "will" about it - if the engine isn't designed to operate on higher octane fuel, then no extra energy will be created
  4. Higher octane petrol "may" release more energy if the engine is tuned to take advantage - modern engines can adapt to some extent but having to cope with EU minimum octane is a disadvantage - raising the cetane rating for diesel doesn't have the same effect.
  5. 100 ml of Millers every 1,000 miles costs a fraction of the price differentioal for premium fuel
  6. That's why high turnover supermarket filling stations have much to recommend them.
  7. The same applies to the big brands - in any one locality, all regular fuel come from the same storage tanks at the local distribution depot with brand-specific additives added at point of delivery to the filling station. The EN standards specify a minimum additive specification - how much any brand exceeds that isn't known as chemical formulae are never published. Believe marketing hype at your own risk.
  8. At home, I use Asda diesel almost all the time, because it's cheapest, but with regulart doses of Millers - occasionally I use Morrisons which I perceive runs slightly smoother - on our present holiday, one fill was Tesco which was definitely smoother and two fills were Esso which was no different to Asda. Despite using brim-to-brim rather than the trip computer, I can't get any repeatability of MPG as the usage pattern within each fill can vary so much - without that repeatability any claims of MPG improvement are suspect.
  9. Keeping the fridge cold is straightforward - keeping frozen food below the specified temperature is much harder.
  10. Why not the fridge, battery charging and ATC as well - that's a lot of amps/power but I'm sure the technology could be specified to cope.
  11. DPFs were mandatory for diesels from Euro 5 and some vehicles needed a DPF to meet Euro 4. I can't explain why the JLR document makes it look like they were introduced for Euro 6
  12. The wording does suggest a product has already been devised and the survey is market research to judge demand.
  13. AFAIK they quickly went bust and the remaining stock was imported from LMC by a dealer in Northamptonshire, including some Australian spec models with HD suspension, roll-out awning and aircon. All I can suggest for the OP is to regularly trawl Autotrader Caravans, Ebay and the other used product internet sites.
  14. Euro 6 generates more EGR failures as they have to operate more frequently to reduce NOx but the changes should have little effect on the DPF.
