Re: 5 W 30, revisited
I use 5W30 in the winter
and then switch to 10W30 in the summer.
Around here the temp drops below -20C in winter
and rises above +29C in summer.

Re: 5 W 30, revisited
I wouldn't bother switching it out, but I would follow the manual's advice
at the next oil change. I would think if I did a lot of severe driving in
high temps, I would lean towards the 10w30, but if you only do a lot of
short trips without getting the engine up to operating temp, then 5w30 may
be OK. If a dealer is using non-recommended oil at oil changes, I would
think they are voiding warranties! Was the oil they used synthetic? If so,
you should be fine until next oil change.

Manufacturers generally recommend non-synthetic 5w-30 for low ambient temps.
Despite the 30 rating, it is less effective and even detrimental at very
high ambient temps. Most owners manuals will recommend a switch to 10w-30 in
operating conditions which include ambient temps abover 90 F.
Synthetics are another matter. Mercedes Benz, for example, recommends 5w-30
Mobil 1 in vehicles using their computerized Flexible Service System.
Depending upon operating conditions (ambient, trip length, average speeds,
etc.) can theoretically recommend an oil change interval as long as 20k
miles.

Thanks! I'll sleep better knowing that. I was worried about it.
