So last week I changed the oil in our 1.8L 2003 Vibe. It has 98k miles. I have used Valvoline DuraBlend until about 80k then switched to MaxLife (5W30).
I noticed it was running a little rough over the past 10k or so. Not terribly rough, but slightly. Every three or four oil changes I'll put in a bottle of "sludge cleaner" (for lack of a better term) since we've had the car (Oct. 2005). I have in the past used a Gold Eagle product I bought from a local repair shop in WI, but can't get it here in KY so I've been using the NAPA Engine Cleaner product recently.
So for this oil change I used the NAPA product, and also used Engine Restore (little silver cylinder can - can find it at Walmart and any auto parts store). It says it restores compression, especially for engines over 50k miles. When I started the vehicle it was almost immediatly smoother. When I drove it, acceleration was better and more immediate. Anyone else have any thoughts on this product?
