Dave...I am starting to question your credibilty with yet another link that tells another story about your assertions of no sludge.......including no lawnmower sludge.
To think you actually started another thread on this forum showing how clean your mower engine was, showed no sludge, and dino/mineral oil was just fine and was all the mower ever saw. That apparently wasn't truth at all. BIG LIE IN FACT.
What in the world is this all about then??? This shows a different """story"""
Just to remind everyone of your other, very different "story"
When connecting the Dots of all your story telling.................it's very disturbing indeed why someone would lie like that and make up all those stories and twist/distort/fabricate whatever information existed or not, Just to avoid admitting synthetic oil is better???
Talk about issues. Get back on your meds....NOW SIR!!!
