If it's not too late, I'd do it. Never a bad idea every now and then. The one thing to potentially worry about, and it shouldn't be a real worry if you do regular changes, is the loosened sludge clogging the pickup screen.

 

Do mine everytime I do an oil change.

 

what is meant by engine flush? Coolant? Sorry if this is a stupid question.

 

An engine flush of this type is a bottle of solvents, basically, that you put in the old engine oil before you change the oil, and then run for about 20 minutes. You drain this oil, so it's not left in their for very long.

It's not an additive, really, since you're not leaving it in. I'd advise it if you are going to full synth. I did it with mine about 3K miles ago, and haven't had any problems. For this one, you might be best off putting a new filter in first when you run it, so it can catch more of the gunk. Then put another new filter with the new oil.

I'm trying to decide if I want to do this again for my next change, which I'm doing in the next few weeks.

could you please specify what type of solvent to use? one bottle only? thx.

I used the AMSOil flush. It said one bottle, although you needed to make room by removing an equal amount of oil - took care of that by putting in a new filter.

I'm sure there are other products on the market.

 

There are a few. Amsoil is the expensive way (but good).

If you can find it, try Chemtool B-12. I believe they recommend half the bottle (8oz). But really, anything you use as an injector cleaner you can also use as a crankcase flush...

 

thanks for the info. i will get w/c ever one i can find.

 

What cleaners are safe for turbo's?

 

I've heard only good things about Auto-RX. There's even a site where some guy did an independant test of the site, but I don't have the link. Search for Auto-RX and you should get bunch of hits.

The one thing about Auto-RX is that it's a long term flush. You add it after you change your oil AND FILTER. When I called Auto-RX, the guy told me to add it in addition to the engine oil. After you add it, you have to drive about 1500 miles, change the oil and filter again, then drive 2000-3000 miles without Auto-RX, then change your oil and filter again, and then you're done if your car has under 100k miles.

I just added it today after I changed my oil, so I can't comment personally on the results other than that my engine hasn't blown up yet.

 

Auto-Rx has a great reputation. I'm using it on a 1997S that was dirty but not severely clogged up. I'm on the rinse phase and will start the 2nd application soon, since the car has over 100k miles. I took before pictures and want to get another set over the holiday break.
