Really? Because there’s a response by me on the first page where I thank SC Maintenance for giving me a legitimate answer. Since then, it’s been nothing useful.

Where did I say that I didn’t want to do it? I asked for someone to clarify what the potential failure mode effects of eroded spark plugs are. All I got was a bunch of ways of saying because the manual says so until one person bothered to actually address my question. Since then the thread has...

I did. And yet everybody and his brother apparently feels compelled to interject their opinion without reading past the first five or so posts in the thread.

Thank you. That’s a legitimate reason. Going to get new plugs in the very near future.

But does that happen that suddenly? Wouldn’t there be excess oxygen registered by the sensor upstream of the catalytic converter before misfire events got frequent enough that you’d be pushing a consequential amount of fuel through the cat? And again - wouldn’t you see a substantial drop in...

It’s actually very easy, but I adopted this philosophy when I had a different vehicle that required pulling the engine to replace the plugs on the rear cylinder bank. I’m just looking for a better answer than “because the manual says so”.

Welding or corroding?

I didn’t come here to argue, I came here to get a reason besides “the manual says so”. Okay, so the coils will run hotter - is that necessarily going to kill them sooner? Will it manifest itself in some other way than a drop in fuel economy? Is there some other indication of worn plugs that is...

Again - I see no drop in mileage. This would obviously be the first indication of electrode burn-back, and it doesn’t seem to be happening. I have a degree in mechanical engineering. I get that things wear out - but I also know that they give indications that they’re wearing out. I don’t...

I’m getting embroiled in an argument on another forum, and I think I want to ask a broader audience. I have a 2019 Mazda CX-5 with a 2.5 L turbo engine that has 140,000 on the factory spark plugs, and is still going strong. I have no drop in fuel economy, nor do I have any apparent misfire...

What did I just read?

Studs on bare pavement are a serious detriment to traction. I’d have to search to dig up the test, but from what I recall, the difference in braking distance on clear pavement with studs vs. without was worse than the difference going from all season to dedicated 3PMSF winter tires. How much...

I bet they’re popular in Philly.

There's a real metric in evaluating tire wear called "turns per mile" that's intended to quantify the idea you're intuiting here. Yes, frequent turns will absolutely lead to premature tire wear.
