Are there any cons of using the 5w50 weight oil ?? Besides the more sluggish feel ? It is tropical here so the weather is pretty much in the 75-95 degrees F region. I'm just wondering if it'll stress the engine or oil pump or anything else.... I remember the manual recommending a broad range of engine oil weights for the box, even down to 30w (winter ??), but not as high as 50w.

ANd is that anything wrong with the mobil 1 engine oil ?? My indie uses that and I'm due for an oil change now...

5w50 is fine. mobil 1 is fine. the additive packages for mobil 1 vary greatly across viscosity grades & people have strong opinions one way or another. as long as your oil change intervals are reasonable, i don't think the additive packages matter all that much. wear is not really the problem in these engines anyway.
