It appears that the thread is turning into, "What car company has the best products."
I find that strange, because we all know who has a better product. Don't we.
I posted the question on the first tank with the mix. I held off posting the change until I had a few miles on fuel blend.
I now have over 1K miles on the truck using this blend. At this point, the MPG increase still holds.
On my 89 Honda Prelude SI 2.0L w/130K miles, I did the two treatments with Auto-Rx. At each of the of the four OCI, more black carbon and sludge would fill the filter and come out with the oil. The carbon and sludge over a period of twenty years became dry and hard in the engine and oil pan...
I just might take a look at the Honda Fit when my 89 Honda Prelude 2.0L wears out.
Those red dots in CR made me buy the Prelude in 1989. lol...
I also hope that fuel hit $4.00/gal this year. Helps keep the roads less congested. Even at $4.00/gal, it's still cheap.
Does it appear that CJ-4 will be an additonal line of oil and it will not be grandfather for older diesels?
If so, CI-4 oil may morph into..CI-4+++++++... lol..
It will be interesting to see what the engine makers say about it.
I have a 89 Honda 2.0L with 142K miles... I did three cleanings and rinses on it and now use the 3oz maint dose. The oil still looks black as coal after 1K miles on each OCI.
I am completely satisifed with the product. The car runs great and I have no oil useage between 4K miles OCI.
I also...
