Re: CRC intake valve carbon deposit cleaner- in a spray can
Good point on using cleaner first then changing the plugs.
Not good to run all that gunk over the plugs.
I only put about 5K on a year so won't be ready for a top end service for a while.
On a side note I am running Shell Premium now to see if there is a difference.
Haven't noticed a change in running yet but the exhaust tips are MUCH cleaner.
I'll give it a couple of months and let you know if there is a change in running or mileage.
