Mario-R Posted August 24, 2021 Share Posted August 24, 2021 (edited) Hi. I recently bought Alphard 3.0 V6 2003. On steady motorway driving 60-70mph max when revs are between 2500-3000rpm, fuel consumption is 20MPG (UK) I don’t think it’s normal? I’ve checked air filter and it’s like new (still white all around) I’ve plugged my diagnostics and o2 oxygen sensors showing I believe normal values between 0.1V - 0.8V. Car is rolling nicely, no brakes seized etc. The only thing I haven’t checked are spark plugs but engine is running very nice and smooth, good acceleration, no misfires etc, no smoke from exhaust even under hard acceleration, drives lovely, . Tyres on 35psi. Anyone know what else I could check to reduce fuel consumption? Happy to hear from you guys what’s your fuel consumption on motorway. Thanks Edited August 24, 2021 by Mario-R Quote Link to comment Share on other sites More sharing options...
