Contemporary road tests suggested 20 to 25 mpg for a series II automatic 735i E23. I have been very impressed with my '85 735i since I put it on the road this month. I regularly get 25mpg & better on a run. I wonder if the OBC is being optimistic? What mpg do other guys get? My 528i E28 usually gets 22 to 25mpg on a run. appears to use more juice than a 735i. is this down to taller gearing/lower revs & the motronic in the 3.5? ------------- Philip '86 E23 735iA SE - Polaris - The Silver Surfer '85 E23 735iA SE - Cosmos Blue - VJ '86 E28 528iA SE - Dia Black - Helga '86 E23 728iA SE - Polaris - The CHAV mobile |

Hi Simon, Is this the red manual 735i from Brighton with the bashed in door? 28.8mpg is outstanding for a square brick of a car. as good as the later shape E32 735i maybe??? ------------- Philip '86 E23 735iA SE - Polaris - The Silver Surfer '85 E23 735iA SE - Cosmos Blue - VJ '86 E28 528iA SE - Dia Black - Helga '86 E23 728iA SE - Polaris - The CHAV mobile |

728i has been averaging 24.5 since OBC working, 50/50 mix of urban queuing and light motorway use. It seems to be threatening me with a rather generous 200 miles remaining though and there's only a third of a tank. Perhaps they're baker's miles where you get one thrown in for every dozen. ------------- Regards Simon 1985 728i SE E23 2004 Audi S4 4.2 Quattro Cabriolet
