And the winner is....? Disconnect the battery. Yup, that did it. Just back from a good spin and she's back down to 15L/100km so about 16mpg U.S., 19 mpg Canadian Imperial. Not great but normal for a 4x4 crew cab. Thank you all for your ideas on that. Still throwing an O2 code on and off. No coolant leaks. Might just need some new ones. I'll have to see which one is acting up.
Going back to your spark-plugs and the anti-seize
I wasn’t this aware of the technical implications….
I mean it’s just anti-seize ? right ?
Spark plug are made with zinc and nickel plating to protect them from the steel corroding and galling inside the aluminum cylinder head.. and though spark plugs aren’t changed as much 100,000 miles still sounds crazy but that’s what some manufacturers attest.
Take it into consideration that platings are surface applications and thin at best, still need to be protected.
Through experience and recommendations you learn not to screw anything into a dry hole.
There is the technical issue of torque values being adjusted.
In the larger picture there is a greater concern than in the past for spark plugs to ground properly because of the increased voltage made through coil on plug and wasted spark ignition systems.
The alternative with all different choices in formulas in anti-seize is to use the ones that have a higher electrical conductivity.
The first choice most assume are formulas containing copper since copper has greater conductivity than most metals, some write in caution from using it in conjunction with a part inserted into the combustion chambers …
“Copper is recognized as a powerful “pro-oxidant.” The contamination of lube oil with copper anti-seize during the assembly of gear boxes, bearing housings, and hydraulic systems creates a situation that may compromise machine performance due to lube oil breakdown acerbated by copper contamination.”
What is recommended is to use anti-seize thread lubricants using combination of nickel and graphites for conductivity and tolerance to high heat exposure

You must use the right spark plug lubricant when changing spark plugs or your engine will suffer.-----------------------------Subscribe:https://www.youtube.c...
