So I generally don't post alot of questions but this will be my first post next to the one I made in the image gallery. I found most of what i needed through the search function which you guys are pretty good with the diys and stickies by the way.
Anyway I just got my CB7 last Friday and during my test drive and talking to the guy that was selling it, he did mention that it was in need of an oil change. So today when I changed the oil, I did note it was blacker than I've seen before and slightly thicker than usual. Of course I drained the oil filter as well and let it drain for a good 15 minutes before reinstalling the drain bolt. It was just kind of concerning to see only 2.6-2.8 quarts in my waste container. I recall reading that the F22A1 engine may burn oil? This one has about 120k on the clock and I'm not 100% sure of the maintenance history besides a brake job last year and a radiator replacement back in 2003 at 51k miles.
With that said I may try to run the Auto-Rx treatment on my next oil change because I also noted that there was some build up on the underside of the oil filler cap and my makeshift funnel when I took it out of the filler. I did fill it with 5w30 Mobil 1 Truck/SUV oil that I had leftover from changing the oil on my 4runner. The only difference I recall is that this has the zinc additive that was removed from most oils a while back. I also noted less engine shake at idle after the oil change. I was just hoping for some feedback on this. I do realize its a 17 year old car but I figure that maybe with some good maintenance maybe I can help bring the engine back into good running condition for daily driving?
