308 Carb plug life

[steve]

Can I get a a feel on what you 308 Carb folks are getting for spark plug life. Maybe in miles and or years. Also what plugs are you using. I'm just trying to see what kind of life there is.
I am using NGK BP5ES and have had them in since 2000 which is around 16,000 miles. Just asking , thanks

Man, it really depends on the quality of your fuel.........that's the heat range and brand I use, as well.

Methanol seems to be loosening fuel varnish in my three cars. Highway driving and upper revs is the solution.....

Don't forget to adjust the gap, down to about .022 or so......the OEM of the NGKs is .035.
Early 308 Manual says '.015 to .025', I was given that .022 by a wise guru....

Many 308 owners have been using the NGK Iridium Plug and like the performance of it.
