Hello everyone. I wanted to get a solid answer regarding the condition of what to do in regards to my motor oil. I have a 95 240sx with a redtop (swapped by previous owner). I got the car in 2005, maybe 200 miles at most.

The car mostly sits due to me not using it as a daily driver. When I got the car I immediately changed the filter and oil with a pureone filter and mobil 1 full synthetic oil. The oil turned black quite quickly. My question is, what can I do? I don't drive the car often at all(NYC roads). At most in the spring and summer only. During the rest of the year it sits and I start it up about once a week. I am also thinking its a fuel issue, the fuel might be to rich. I also thought about putting one quart of atf fluid, but don't want to risk blowing a bearing. My best self suggestion is to run synthetic, but this won't do much help because I BARELY drive the car. If I would have driven the car more the synthetic would have slowly cleaned the internals, due to synthetics nature. At this point im stumped :confused: . Any suggestions would be greatly appreciated. Thanks

put atf in place of oil. same amount as a regular oil change and put in new oil filter. Start car ONLY LET IT IDLE DO NOT REV AT ALL. Let car run for 5-10min. and drain. Then perform normal oil change.

your oil is getting dirty because it is started up often but not run through a drive cycle every time. The oil is just accumulating fuel (especially if you're running rich) and other crud every time you start it and it isn't getting hot enough to burn anything off. IMHO, i'd just do an oil change, disconnect the battery and leave it untill the weather gets nice.

The leaking fuel injector sounds like the problem. The oil is brown, when the engine is cold but black when driven. I'm going to try to do more frequent oil changes and see if it helps. Maybe I might add some atf to loose some debris. I don't want to flush, just in case there is gunk and clog the oil passages and oil pump pick up screen.
