Changed the oil and filter on my 190, decided to try fully synth 5w 40, I know there are thoughts either way on this.
I used a can of Wynnes engine flush first and did exactly as it said on the tin then took out the plug and left it for an hour, it was up on two pallets (one under each wheel
) only because it gives more crawl space and of course as the drain plug is at the back it probably helps to get a bit more old oil out of the sump, filled and fitted a Framm filter, sump plug back in then filled with triple QX 5w 40 synthetic oil (acea A3/B4)
Now it may be my imagination, but I'm sure it sounds a bit better, It seemed to me that I could hear the burble of the exhaust a little more than before (because the engine is quieter) and possibly a little more of the (normal) sound of the belts there certainly was no tappety sound or rattle as has been described by some other V6 owners.
I'll keep a close eye on it and see what happens
