Does anyone recommend this? I have 62k miles on my TL. Pros and cons.

 

what does it do?
The masses here like seafoam and bg44 for cleaning the intake system
The oil should not get any mileage-slippery-thickeners stuff added to it-

vtec operates on oil pressure changes, so you do want to run an engine cleaner thru the oil right before a change now and then.
In my opinion and as proved by members with over 200,000 miles onthe motor

 

It's supposed to clean sludge and grime from the oil system.

 

may I suggest you read any of the Seafoam threads here- 1 8oz can in the engine oil before oil change will clean it right up- also used in intake mmanifold vac line, and gas tank- cleans everything

If you suspect sludge- replace the oil filter before treatment- so a fresh one can catch all the bad stuff you will dislodge.
According to their directions on website- you can drive with it in the engine as long as you closely watch the color on the dipstick and change the oil when its bad.
Many ziners run it 5 minutes at idle- others drive 15-30 minutes.
