From personal experience(2x doze) AutoRx will not have any effect. Only thing that could possibly work is a piston soak.
40 weight oil & 3k OCI would keep the consumption to minimum.
Aftermarket for Isuzu is almost non-existent.
An Isuzu tech has confirmed that the replacement rings are indeed new/redesigned.
Independent places by me charges around $75+/hr - the $250 will be gone as soon as they pop the hood.
Funny that some folks always assume that the motor will explode soon when a motor starts consuming oil. My 99 has 180k+ now;it started using oil around 60k;just keep an eye on the oil level.
Clean the egr valve and tube using carb cleaner;suck seafoam into the intake and do a cylinder soak. Go...
I am reluctant to go 7.5k OCI, flash gets too low for my taste. Perhaps I would do a filter change/top off at 3.5k if I go this route. I suspect I could get same result with the 7500 on same miles for half the price.
AL, yes the copper(and Iron) is indeed coming down on every change. 20 weight...
3.5L SOHC V6 VTEC,FWD/AWD
5sp Auto, 260hp
OEM air filter - original/new halfway into OCI
PureOne PL24458
Oil Fill - 4.5 qts
similar wear result from previous uoa(20 weight) even though this oil has less(calcium, etc);refilled with 5w20 M1. Will try MDC 7500 5w20 on next interval.
Should have just kept the broken windshield until the car gets junked in 2 years.... (suspensions is shot and tranny is starting to wear out, saw some copper flakes in the pan)
Excellent result for a dirty breaking Honda v6 motor. IMO, silicon is due to break-in. What is the OCI time? Driving type? Any mileage comparison to oem 20 weight oil?
I am beginning to believe that these 3.5L motors gets a bit better wear on 30 weight oils.
What would the driving conditions be? What is the recomended OCI interval?
Anyway,IMO, I would dump the factory fill at 1k, refill with Exxon Superflo or Mobil Clean 5000 5w20 then dump that at 3k. I would do 2 more OCI's of 3k miles. Then do the 5k/6 months interval and get an UOA for guidance...
I have an '05 TL 6-speed and will do the first oil change this weekend (it has about 5,100 miles)
I'm surprised that you kept the factory fill for that many miles.
I'll be sticking with the oil change interval recommended by the MID/computer
How does the computer calculate the desired OCI?
Looks good. Fe is surprising low especially with M1. Honda v6's do spit out a lot of copper so IMO, it is not major concern but with 40k+ miles, I would have expected the value to be in the high teens. I don't think these motors are candidate for extended drain(normal service-7.5k) especially...
It seems that short trips = fuel dilution for these v6 Honda's which I suspect contributes to the high(er)lead,tin and low flash.
What is Honda's recomended OCI for this driving scenario(severe)? Mileage wise, how does the 20 weight compare to the 30? It would be interesting to see how GC...
