Hi everyone , I watched the video “The end of Toyota Reliability”, and you was using ATS Chemical 505 CRO to clean the engine. I noticed you talked that you let that additive in the engine idling at 1500 RPM (in another video, you were using same product for a Volkswagen at 2000 RPM).
My question is: what is the RPM for a normal idling car, and how to adjust it for different scenarios, in this case, just for cleaning engine using 505CRO.
Thank you for your time and appreciate your help.
normal idle is in the neighbourhood of 700 to 900 RPM depending on the engine.
Scotty was probably raising the engine speed just to work the additive through the crankcase. The RPM doesn't need to be exact. It's difficult to hold it steady anyway. Anything around 1500 is reasonable.
Adjusting idling is done by pressing the accelerator pedal, or by pullung the throttle activation wire from-under the hood (if there is one).
Normal idle RPMs have already been mentioned by MountaniManJoe above, and they also may vary depending on whether the engine is cold or hot.
However, I personally do not like increasing idling speed for prolonged periods of time, cause I believe that this does not do good to my engines (e.g. it stresses the cooling system). So each time others would increase idling RPMs, I prefer to just drive the carsw around with virtually the same RPMs and results.
Thanks guys for the input. I will just probably rev the engine gently to 1500rpm for a few minutes to work the additive through crankcase for a few minutes, and will just idling normally for the rest.
My toyota 2AR-FE (done around 55k miles) does have a little rattling noise when cold start, but for very brief moment (like half a sec). I’m aware that lots of people with same engine have the same issue, but they will run just fine for a very long time. The car still drives very comfortable and quite but It’s just annoying for me, so hopefully this 505CRO addictive can make it better, if not I will just drive it as it.
