Tips on increasing MPG

[JOWETTJAVELIN]

You won't need an alternator for an electric fan, the reason being it is simply a motor not doing much much work (unlike the wipers which draw far more current) and the fan will be on only when the temp creeps up - hopefully not too much then.

Alternator belts need to be much tighter than dynamo belts.

You live and learrn, I wondered because I had a bitzas once that had the Rover SD1 electric fan wired through the same fuse as the high beam and needed a 30 amp fuse fitting before it would stop blowing.

I think the research has already been done by people with much more money and much better facilities than we have.
Is there a modern car that doesn't have an electric fan?

[moggiethouable]

Well, chains have made a comeback over cam belts and replacement paper filter elements instead of spin ons for oil too, so you never know

[chesney]

Isn't that just because these are deemed better for the environment?

[MarkyB]

Cam chains can last the life of the car if properly specified, as Chesney says environmental reasons probably explain the return to paper elements.

It would be lovely to think that car companys sat and detailed all the parts with the environment in mind, but its more likely they want the vehicle back in the garage for servicing,or that it just worked better.
Environmentally it cant be better to add an additional bearing, housing, motor, thermostat and electrics to power an electric cooling system can it?
Call me an old cynic but selling cars is their raison detre and dealers want you back for service,certainly if modern cars mean reliability to such an extent that you never go back for repairs.
Its a difficult quandry for them, to build a vehicle that has longer service intervals and is more reliable than the competition,meaning less revenue in spare parts and servicing, but continuing to sell cars to make a profit and survive when the average joe does not want to be swayed in to buying prematurely what he recognises he doesnt need.
Creating the want to override the need is the key .
See, youve set me off on one,what was the thread? ah yes how to improve fuel consumption.........stay on the computer

[MarkyB]

The market modern car makers are mostly aiming for is the fleet market where service intervals and costs are important considerations.
Certain things are now be coming law with regard to the recycleability of the materials that cars are made from too, this will have more weight than any environmental thoughts they might have.

Magnets on the fuel tank?

[MarkyB]

Indeed, remove any magnets or other unnecessary weight from the petrol tank and elsewhere on the car.

maybe it's miles per penny that counts

so save coupons from supermarkets ,ETC

I also have an app on my phone which looks for the cheapest (not always the best ,I know)

very useful if you drive an LPG motor ,as you can see the locations that sell it
