IT CLEANS--- Motor Medic Motor Flush

I used to have a devil of a time in some older vehicles with carbon accumulating in the oil scraper ring groove and apparently increasing oil consumption by keeping the ring from expanding fully against the cylinder wall (i.e., "stuck rings"). The Prius engine design IIRC involves low-tension piston rings to decrease friction loss, but having low-tension ring could exacerbate the problem of carbon accumulation in the ring groove preventing full oil scraping. Could this motor medic stuff (or any other strong solvent) help oil consumption via the mechanism of removing carbon in the piston ring grooves? Plausible or not?

 

That's what my testing is confirming .

Using BG Products EPR and seeing less oil consumption.

 

Yikes, Red Line is some spendy stuff...not sure I can justify that price. However, if it works...

 

After about 1500 miles on this oil change with Red Line 5w-30 and BG Products MOA I have not had any decrease in the oil level on the dipstick!

I'll update as the miles increase on this oil change interval .

 

Wow very interesting! If your updates continue the trend...I guess I might have to try it.

As a side note, I am back to driving our 2010 Prius as my daughter is off to college. When I drive it, I'm not seeing nearly the oil consumption as when she drives it. She doesn't treat the car nearly as well as I do ( a lot of 'fast starts', etc...) ..so that is the obvious reason why.

 

I think I may try some in our 2010 this spring.

BTW - Amazon seems to have a really good deal right now.

Edit : Rereading the entire thread scared me off a bit.... Of course, discussing *any* car product is like discussing politics/religion so who knows.

 

You’ll get chastised .

But give it a shot.

How many miles you up to now on your Prii ?

BG Products keeps working for me.

 

'Couldn't hurt'..right? ....or could it? They do make a 'synthetic' version which is supposed to be 'better'. However, it is nearly the same price as the BG flush.

2010 liftback has around 125K or so...but I need to check to make sure. Son is mostly using it these days. Oil burn is about what is was before and I've given up trying to mitigate it...not worth it. However, like I said..I might throw some engine flush in when springtime comes. I will say that the car looks brand new now after body work,etc.. from his accident ( he was 0 percent at fault ). There is a thread somewhere about that too but I'm too lazy to look it up.

I'm driving the 2012 Prius v (wagon). No noticeable oil burn yet that I can see. Almost 150K on it. After my car care saga over the spring/summer ( see thread in signature ), I was a bit burned out...especially because of the full front suspension rehab project...so I never got to the EGR maintenance, etc..this year. All that stuff is overdue on the Prius v (wagon) and is scheduled for this spring.

Oops sorry that was more than a bit off topic.

 

I’ve given up on trying to quell oil consumption and have progressed to management of the situation as well.

I’ve clubbed up to 0w-40 and it is running smooth.

Consumption still around a quart every 4500 miles or so, which ain’t bad at 193 k miles.

I’ve got at least 2 more egr circuit cleanses lined up out here for members next year already, so I’ll be very familiar with your planned maintenance .

 

I probably said this earlier in the thread but................

Engine flush products are solvents.
No car maker or oil company that I know of recommends putting SOLVENTS into your engine along with the oil.

If it does a really good job of loosening sludge, large pieces might come loose and block oil passages.

Sludge that is firmly attached to non-moving parts does NOT cause a problem......as long as it stays attached.

 

Yep..hence my hesitation...

 

Any update on oil consumption or lack there of ?

Curious if you notice a color change (darker used oil, etc.) when using the MMMF, or was that only after the initial use ?

 

Ok you convinced me...I think?

 

Have any of the 'cleaned' vehicles (yours or others) noticed a reduction in oil consumption?

Given that MMMF isn't generally used as a piston soak, do you feel it might work in that application?
