2006年4月21日 · The european / american cars are a bit different because they have to cope with a summer / winter blend of fuel. Not a good idea to run ULP in a car made for PULP. You may be able to get away with it if you have a octane booster bottle in the car if you get caught where there is no PULP. Check with the manufacturer first though.

2014年4月16日 · So most fuel stations will sell unleaded (95 ron) or premium unleaded (98 ron) and a few places sell high performance unleaded at 101 ron. It is interesting to consider some history here. In the days before ULP, we had Standard (89) and Super (96). Most contemporary cars used Super. Enter catalytic converters and the requirement for unleaded fuel.

2013年10月10日 · A higher octane fuel can withstand more compression without combusting. Higher compression ratios allow the engine to extract more energy from the air fuel mixture which equals more performance. Essentially, an engine designed to run on 90 RON ULP will happily run on anything that is of a suitable quality and 90 RON or higher.

2013年7月11日 · The Fiesta can run ULP fine but if you read the Fuel consumption rating it says those figures are obtained on 95 PULP. On the work cars we only use ULP due to thats all we can put on the fuel cards and they have a noticeable knock/ping in certain driving situations and my car also had it when I got it and used ULP in it but since going to PULP ...

2012年12月6日 · Often there is a pre-set ignition map in the ECU, and it switches to a 'knock map' if a poor qualtiy fuel causes knocking. There is generally a fuel trim which you ECU can adjust on the fly to keep your engine running at the correct fuel mix, but this is irrelevant for different octane fuels, as is cam timing adjustments.

2014年11月24日 · Cheap fuel leaves so much deposit on the O2-Sensors so that they have struggle to give correct readings. Tyres also play a big part in fuel economy. Good brands of tyres are tested for fuel economy and can save 15% on fuel-economy over cheap brands that get no testing. Honda Engines are designed for Premium ULP.

2012年1月28日 · The fuel system is simple if a hose wears out or an injector leaks ill change it. Main reason is local servo doesnt have premium, but the e10 they have is 95 octane and the cheapest. The car pings its head off on 91 so cant use that.

2024年10月30日 · Fuel trim is irrelevant for RON as 91 and 95/98 have the same target ratio. Fuel trim is entirely governed by feedback from the oxygen sensor(s) in the exhaust system. Studying those numbers is a valuable tool for working out if the engine is running ok, eg if you have air leaks in the intake system you will be able to pick that up.

2012年1月14日 · Most diesel cars,trucks fuel cap/flap are labeled "Diesel only" while the larger nozzle pump are labeled "This is a Pressure Pump". The larger nozzle is heavier plus the hose is lager. You have to look for the smaller nozzle pump generally they mixed in …
