How Do These Spark Plugs Look?

normal wear to me also.. nothing to be worried about.. You would be suprised how long OEM toyota sparkplugs last. going over 100k is pretty common for toyota plugs.

I mean, if they really wanted to make money off us, they can easily say R&R every 30k miles. I feel technology these days has definitly improved within the last 15-20 years. Oil changes are now every 5k, T-belts 120k also now. Fuel filters are never changed cuz now most are in the tank. No more distributors. I think Toyota is nice enough to not rip us off that bad =)

Actually no.
Auto maufactures are always telling the public that their cars are more maintenance free than the compitition's. It just plain marketing.

This is why they are all telling owners to leave things like oil and plugs in a bit longer than they should. Those are the two main engine maintenance items.
Once one maufacturer does,they all have follow to stay competitive.

Yeah, modern oil and plugs have a longer sevice life than in the past.
However, the maintenance schedules are pushing the limits a bit....IMO
Maintenance schedules are designd fot "normal" driving but, few cars fit that catagory exactly.......more marketing.

Yea, in a way i do agree its a marketing thing, and they may be pushing the envelope a bit on certain things. I would have to say when I was a Toyota tech and then a Lexus tech, when doing certain maintenance stuff like your 120k and 150k, you get to see how long oem stuff lasts.

another example, O2 sensors are disigned to be replaced every 30k miles (I think its actually 15k but I know its a rediculous now number). Who actually does that until they go bad? How long has your o2 sensor been on your car?

Hell, now toyota has a the Pink coolant that you are to NEVER flush. There is no interval for coolant replacement. It lasts as long as the car does, and i have seen the same stuff in a 120k car (with little to no problems)

IMHO, I feel technology has made a huge jump. I've seen it with my own eyes and I am confident in leaving my oil in my car for 5k miles or even 10k miles, with a filter change every 5k.

A crazy little tidbit is that I recall back in 95 I was at work with my parents 86 corolla and I kid you not...187k on the car with factory plugs. I go out to the car to start it at 2a.m. after my shift is done (thankfully during the summer in Northern Maine) and it wouldn't start. Come to find out part of the porcelain on a couple of the plugs had just about turned to dust. I was floored that my dad never checked them at all in the life of the car to that point, but he said he never did cause he believed in Toyota quality...what a hoot!
