Agreed. The iridiums are expensive with the only benefit is a longer service life. No additional power, still a spark to ignite the fuel /air mix,....... 1,000,000 fires in 1,000 miles.
I suspect if you run the cost/mile you may discover the iridiums are more expensive per mile. Example...
Something to think about,
Each spark plug will fire about 1,000,000 times in 1,000 miles.
Everything has a life span. If Toyota recommends replace at 30K, (or whatever is in your Owner's Manual) then just do it. Plugs are a pretty inexpensive item. You'll spend more on oil changes than on...
FWIW, I use the copper based anti-seize between the steel plug and the aluminum block.
Only need a small stripe on one side of the threads. Don't go all Rembrandt. It will spread into all the threads as the plug is screwed in.
Every walk the dog's legs, pads, butt, ears, muzzle all get inspected any awn found gets removed.
I average 4-15 awns after each walk. Been to the vet to get one removed from between his toes, cost $300.
Today, my truck was a concrete hauler and assisted in pouring a pad for the AC unit.
Then later it was an Ice cream truck and helped me find a chocolate milk shake.
Next weekend it will be a storm debris hauler making runs to the landfill with fallen branches, logs, brush, dead trees...
Run on I-35 or I-80 at those speeds. You'll find an IHP. I'm sure he'll be nice enough to introduce himself to you.
But considering how fast and how sound your Gen1 is, you should be able to out run any IHP.
Good grief. Those statements are so weak minded........
I'll wager they swiped the Owner's Manual just so they could rotate the tires how they desired.
Jay, be aware. If you get stopped in IA at 20 mph over, then you will get a hefty fine possibly impound the vehicle.
IA is one of the states which strictly enforce the speed limit.
Don't screw with the IA Highway Patrol.
Jay. Check your Owner's Manual for Toyota's recommendation on tire rotation. Follow that.
If your favorite DT is doing something different, then show them the OM.
I just picked up 18.18 gallons to cover 346 miles, yielding 19.0 mpg feeding a 4.0 L, 4400 lb Gem2 burning E15. I could prolly gain an mpg or 2 by shifting to E10, but E15 is less expensive.
Thanks just the same. I'll hang onto this Gem2 and smile at the fender flappin' Gen 1s as I cruise past.
Radial tires are typically "rotated" front to back on the same side. Rarely do radials use the old bias ply tire cross pattern.
Besides, my tires rotate every time I drive.
