Hutch 14 Posted December 30, 2013 Report Share Posted December 30, 2013 Hi, I'm gonna be driving just over 1000 miles next month and wondered if you guys have any suggestions to maximise MPG (temporarily). I'm used to classics and when prepping my GT6 for 2000+ mile trips I'd do things like over-inflate tyres, use cooler plugs, tweak the mixture (and even removed a carb once, from 3 to 2, which took it from 22 to 28 mpg!). I realise I can't do the same things on the VR6 as it's largely down to mapping, but any suggestions appreciated Link to post Share on other sites
Lukey. 381 Posted December 30, 2013 Report Share Posted December 30, 2013 Accelerate fast to speed an hug the arse of lorrys, works wonders Link to post Share on other sites
Funky_monkey 2 Posted December 31, 2013 Report Share Posted December 31, 2013 Definitely slip stream lorries if it's dry, but if you get stone chips, move put! Usual no air con, heating, radio, windows and sunroof shut and stick to 70mph.Remove any excess weight in the boot. Link to post Share on other sites
Hutch 14 Posted December 31, 2013 Author Report Share Posted December 31, 2013 Ah yea slipstreaming something that looks like it can't brake quicker than you+reaction time Hey I wonder if using one of those curvy Asda lorries works as well as a brick shaped one? But forget that, here's more serious question: anyone know how MPG is calculated by the dash readout? Is it a best guess based on throttle position and gear or is it actually measuring engine load?

Marneus 78 Posted December 31, 2013 Report Share Posted December 31, 2013 If I stick to 70 in my auto I get around 33mpg, which I don't think is too bad. I'm hoping to get the same next year when we do out honeymoon/euro trip (3700 miles in 7 days) Link to post Share on other sites
Swivelonit 119 Posted December 31, 2013 Report Share Posted December 31, 2013 I sat at 56 mph with the trucks in mine, the MFD showed I the MPG to be 38 mpg, journey took an extra 30 mins by driving slower. On the way home I sat at 75 mph using cruise control and MFD showed 29 mpg but we got home 30 minutes sooner. So sacrifice a little time and you will save a fair bit of fuel.

rodney 17 Posted December 31, 2013 Report Share Posted December 31, 2013 just to add the same really. There are links for hyper mile ing as it is called and I dont agree with some of the things like higher tyre pressures.. but hey... items to look at.. Streamling. Accelerate to speed quickly and remain at constant speed like your life depends on itDont brake - think of it as wasted energyturn off electrical items not neededremove all excess weightHigher RON fuel is a discussion pointservice the car... fullyA sports exhaust can help along with air filters but get made to measure rather than off the shelf to ensure you dont get motorway boom.you can get a remap and this can also help. (I got better mpg once supercharged than before fitted on runs)slower speeds Finally stay off the beer for a few weeks so you have the extra cash and just drive it like you should!! My preference overall.. Njoy your trip Marneus 1 Link to post Share on other sites
crowd1972 0 Posted January 5, 2014 Report Share Posted January 5, 2014 Filters and exhaust plus service , slip stream big lorrys and stay under 60 mph if your not bothered about travel time , took pic to prove at tuning werkes croydon I got 41.2 mpg from mfa .

UnitedMotorsport 55 Posted January 5, 2014 Report Share Posted January 5, 2014 Research that we are doing at the moment reveals that the brand of fuel used is a massive player in over all fuel consumption. The RON of the fuel is a by product of what is added to the fuel, so the RON of the fuel isn't directly helping with consumption. Link to post Share on other sites
Lukey. 381 Posted January 5, 2014 Report Share Posted January 5, 2014 so whats the list of the best fuels? Link to post Share on other sites

crowd1972 0 Posted January 6, 2014 Report Share Posted January 6, 2014 United motorsport are quite right , I have found that shell optimax and wurth octain boost can show some high mpg on m way if driven sensible , but if your engine not right to start with then you wont see much improvement plus I am a big believer in luck of draw with engine from factory some good and some just couldn't wait too get rid of , owned 23 /24 vr's.

ssaunders 199 Posted January 10, 2014 Report Share Posted January 10, 2014 How about finding a cheap diesel 5th gear and swapping it, 70mph@2k?S Link to post Share on other sites
Lukey. 381 Posted January 10, 2014 Report Share Posted January 10, 2014 If looking at changing the box ratios, what about the sixth gear conversion, expensive though, and rare Link to post Share on other sites

Russ_vr6 12 Posted February 16, 2014 Report Share Posted February 16, 2014 Alot of it is driving technique-learning how to use the throttle-for example when travelling at a set speed, backing off throttle a touch will keep you at set speed but reduce fuel consumption-but it sounds like you know what you're doing driving wise.I'd be doing the basics:Making sure tire treads are good, matched and correct pressureServicing - fullMake sure tracking is set correctly-even a tiny bit out will effect. Loose as much weight as possible-all junk, ,unessasary items.Good quality fuelMaking sure the car is up to operating temperature - a sticky thermostat can drop mpg as the car will think it is cold-more fuel usedI have no doubt mid to high 30's are doable VR6Pete 1 Link to post Share on other sites

craggsy 91 Posted February 17, 2014 Report Share Posted February 17, 2014 The MFA on the mk3 is rubbish anyways and only to be used as a guide. Mk4 MFA uses more things to measure mpg so is more precise.I always work the maths from how much fuel input in/ or fuel tank size to miles done. The R does respectable on a run even sitting at 80 or 90 in Europe. Motorways are its home Link to post Share on other sites
Russ_vr6 12 Posted February 17, 2014 Report Share Posted February 17, 2014 I've always found the mfa to be very accurate-normally within 1 mpg or so Link to post Share on other sites
