I have an '03 'Burb now at 56K. I've never really been concerned with the whole piston slap thing. Every now and then I think it may be happening but I take into consideration that it is a V8, whereas the last 4 vehicles I owned and the other 2 vehicles I currently own are V6 engines and I would expect more noise from a V8.
It saw dino for first 30K, then switched to Mobil 1 for 8K or so intervals. Switched again to GC green flavor after 2 M1 changes because of this darn site
.
Then, 600 miles ago I switched to PP 5w-20 because
1) no more GC green in my area
2) PP deal at Advance Auto, blows M1 out of the water price wise
3) vehicle is not driven daily, often sitting for 5 days, and when driven a lot of the times it is used to transport hordes of kids to-from practice/school/etc. where the engine barely gets up to temp, therefore I thought a 5w-20 oil would be a good idea
Needless to say it was a bad idea.
Piston slap at startup is the most noticeable it has ever been, almost scary. I will be going to PP 5w-30 this weekend, weather permitting.
Should I change the filter (Mobil 1 filter with 600 miles of 5w-20) or am I okay to leave it on?
