Mileage less than you expected?

I would say between 25 - 30 mpg would be considered ok. You can improve it a little with a good service and tune up. Clean out the carb, change plugs, points, dizzy, leads, oil, filter and one of the most overlooked but important mpg culprits, the air filter. Set up the carb properly or get a tuning specialist round. A guy I know does a full krypton for about 25 quid. Well worth it.

Oh yeah I forgot, It is an 83 motor. How many miles has it done?

I would say anything over 110k is gonna be a bit lower on the mpg than say a 50-75k motor. It also depends somewhat on the motor itself. ie cc

Welcome ttom. Maybe the forum can change your embassement to pride? ;) 40mpg is a little high to shoot for without converting to diesel. Be glad you sussed out the CIS by yourself & the bible. You now understand it much more than if you had just cookbooked it with Q&A to the forum and no deeper knowledge. You've probably already checked it, but if you're running CIS-lambda or CIS-e, make sure you've got a properly functioning 02 sensor hooked up so that you're running in closed loop. If the '83 engine is a 1.8, that'll knock your milage a wee bit compared to a 1.7. Your biggest problem may be "...surprised how well it runs at 70 or 75 mph." :D These things have the aerodynamics of a brick, so higher speeds eat into the mileage quickly. If your '83 5-speed is of the overdrive-type gearing, 75 is putting you right at the torque peak, so the engine is really responsive. You may want to keep an eye on the "fuel economy" thread that Wagenryder just started in the "VW discussion" forum. My guess is most gas milage claims there will vary from 25 to 35, with most clustering around 30 depending on driving conditions/styles -- those actually getting less than 25 won't be caring about keeping track of their mileage. ;)
