Hi,stupid Q about gapping plugs

Hi thanks for all replys, even the DUH!!! ones(towards me).

If I am to gap my vehicle at 3500 will it save gas if I gapped at 3200?? I know it will eventually make my vehicle run like doo doo right??
Thanks I was told this but scratching my head about it.

Have a good day thanks for all replys again.
I know why they invented specs also.

Huh!!!!!!!!!!.

I'll take it as of 0.35" and or 0.32" on sparkplug's gap. If your car/ truck's spec call for 0.35", I'd set them at 0.34-0.35", 0.32" is to me too tight and it may not run right. Any running problem will effect on gas mileage. One of the way to save gas is go easy on the pedal.

would just stick with the manufacturers specs as changing the gap isnt really going to affect gas mileage and it generally has to be way out to even affect performance.

Don't you think if a particular setting optimized fuel economy that's where the manufacturer would tell you to set the gap?

Someone needs to learn how to express decimal measurements! The above should read .035", .032" and .034"

It's always best to use the factory specs.

It was my understanding that the wider the gap the better the burn hence more hp and improved fuel economy unless someone else knows otherwise.

Most modern enigines are gapped at around .045, .050 to.060
That's a wide gap.

With today's lean fuel mix in the cars engines there is a chance there will be miss fire because of no spark because there was no free ion between the spark plug gap at that time. The wider the gap on the plug- the more chance of a free ion to initiate ionization and get the spark. Problem is that more voltage is required and more maintenance required because the higher voltage is hard to contain and it is hard on the wires.
For good mileage I am a believer in changing the plugs and wires on a regular basis. Just because it is running don't mean its running to optimum efficiency.
