Be very careful using these motor flush things. For an engine that is half way to the grave, yes it is not as harmful to try them. As you are going there anyway. And the risk is less then the neg outcome can be doing nothing. But for an engine like yours, that just has the common tick/tap in valves after sitting. A few more frequent oil changes is far better. And very much might save the eng if it does have some major issues, but not life threatening ones. You really have to be careful of transfluids or super clean 20 mins eng flushes. As they can and will ALSO flush(more detergent) your rings right out of the eng. If you got gummed up but not bad rings, or rings that are sticky but not noisy. You will in too many case but not all, blow the rings out and clean them off too well. And then you got blow by and smoke all the time. And lower MPG form lower COMPRESSION. Like I said for a WELL taken care of eng. One that has a slight issue with ticking when it sits for a period. Start it up drive it easy but not your grandmother(up to 3500 rpms, over is bad) for ten mins on way to work or mall. And I bet in ten mins or less it is rock soild silent. That is perfectly fine in our vechs. If after ten mins it is STILL ticking then you got troubles more then you want. And if the less then ten mins/three miles and quite works then MORE FREQUENT OIL CHANGES is the cure. And better or DIFFERENT OIL too. Both these will flush out in time the sludge but not the babies bathwater. Mine right now run like crap on Mobil 1. And I bet if I went back to another brand, it would run well like always. I plan to at the end of the 3500/3-4 month. First time and last time. I have had good luck with CASTROL/QUAKER STATE/ WALMART synth. And have heard that Mobil 1 has this problem in some vechs. BTW I care less that GM puts it in OEM in Corvettes nor that Porsche puts it (10 qts) in every 911(996) rolling off the line. If it does not work well in MY vech, whom cares waht they do. I do not own a 911(993) anymore.
