jeremy, sorry. I was just having fun. I wasn't getting "pissy" at all: notice all the smilies in my post? I don't think I fit in the blind or uninterested category in the least, though. I certainly don't have a problem knowing the condition of my oil by looking at or smelling the dipstick. However, I do think changing it every 3k or less is better for my engine, regardless of how it looks on the dipstick. But I didn't mean for you to take my silly reply too seriously.

I realized that. I was just giving the reason why I feel it's better "my" way. Yes, I am more concerned with the high temp oil performance: in the summer.
"I use the lighter for the opposite reason you use the heavier... I'm more worried about cold start friction. I may be wrong, but it sounds like you are more concerned with your oil failing at higher temps.
To me, it's more a case of matching the oil temp range to the expected high's OR lows. In the colder temps, I'm with you: in the fall I'm concerned with the cold start friction, so I use 10W30.
Once our short little summer arrives, I expect highs above 30C, so I change to the heavier oil. Then, yes, I'm concerned with the higher temps.
I just do my oil changes in accordance with the season, given our extremes. But that's just me: as I mentioned, you guys may well be right and the switch to the heavier grade may not be necessary. Have a good week!

However, with thinner oil you'll have more oil flow for a given pressure, meaning better bearing and rotor cooling. Also, thicker oil has more resistance to flow, so even though you may have 85psi of oil pressure at the regulator, thicker oil will have LESS pressure at the bearings than thinner oil because pressure is lost in trying to pump the oil through the passages.

Oil is yer engines blood. The filter is its liver.
...Very important organ; The liver is. I still don't see anyone talking about what filter they use and how often they change it.

Hey, Sterling said that last one not me!
If the oil level goes low it should still not affect oil pressure as long as the pickup never gets uncovered. Oil TEMPERATURE might be affected though... which is why it's always a good idea to have an oil temp gauge so you know for sure. ALso good for knowing when your engine is fully warmed up - oil temps lag a LOT behind coolant temps!

when the car was my daily driver i only used castrol gtx 20/50 and fram or puralator oil filter, changed every 3000 miles of course.
then when it started becoming a race car on the weekends only mobil 1 15/50 synthetic and tall puralator filter, changed before each weekend. premixed castrol 2 stroke oil in the gas tank.
