I decided to see how far I could run the Amsoil HDD in my 2007 F250 with a 6.0L diesel. I sampled it at 5,587 miles and it looked great(that's the immediate previous results on the UOA). After that sample I added 8oz of Rev-X additive just to see what it would look like in an oil sample. I don't have any romping problems in my engine, just curious about Rev-X more than anything. Well I lost my nerve after a long 2,260 road trip done in 4 days and with the coming hot summer, I changed the oil. Looks like a waste, could have gone longer.
What do y'all think?
