Oil Temp Survey

You mean not necessary to go that small? Because 12 is pretty small. The 'regular' size is 19 row.

yea I didnt want to go 19 cuz some guys in the winter have to cover part of the cooler so as to let the oil get hot so I figured a little smaller and I wont have to do that and it will still keep the temps down to a respectable level as I will never run on a track other than a 1/4 mile once or twice.

No no, no ownage. I think what Zsteve is trying to say is that he wants to go with a smaller than normal cooler to avoid having issues with bringing the oil up to temp in the winter, and Lou is saying it's not necessary.

If I'm reading this right, then I agree with Lou. Zsteve, I was really worried this winter because of how long it'd take my oil to come up to temp. In fact, some mornings it'd never come up to 180 because I was short-tripping. The big worry is hydrolysis, which means water in the oil. That's what happens when your oil fails to run at a high enough temperature. Water in the oil can cause internal corrosion, etc. Well, I was running Redline, and I recently did an oil change and sent it off for UOA. The UOA came back reporting 0.0% water. So I think you can run a normal-sized cooler and not have to worry about hydrolysis -- as long as you're using a good quality synthetic like Redline. If you're using a conventional oil, then the risk of hydrolysis due to low oil temp is probably significantly higher.

But the smaller one should still be good enough to keep the temps down right?

Well, even with my 19-row I can get it up to 200-210 if I hit stop and go traffic. That's in GA, and I haven't experienced Summer with my oil cooler yet (I only put it on in Oct.). Once Summer hits, I wouldn't be surprised to see 230 if I start driving hard or get stuck in traffic. And you're in Texas. It gets even hotter there than in GA, if I'm not mistaken. Honestly, I'd just go with the regular 19-row if I were in your position.

I think you'll be fine...I blanked off mine this winter leaving 12-13 rows clear and it was just fine in temps from 30 to 65+. A 12 row will just take the edge off in the summer which is all you are looking for..

Maybe you need an oil "heater" for the winter season. Read this:

""Some experts estimate that the wear on the rings of an internal combustion engine is as high as 0.001" per 1000 miles of operation when the oil temperature is below 170 degrees F. If the maximum allowable wear is 0.006", how long can you run your engine when the oil temperature is below 170 degrees before you wear it out?" (A 6-to-1 engine-to-wheel reduction ratio, an average running speed of 3000 rpm, and 14-inch wheels 28 inches in diameter are assumed.)"

Anyway, oil temperature is not consistent throughout the engine. I would guess the oil draining/flung back from the underside of the pistons (this engine has piston cooling) is a lot hotter than 280 deg. Also, oil draining back from the surface of the block is no lower than say the temperture of the engine coolant of say 190-200 deg. That said, it's obvious the oil drains back to the base pan where the different temperatures mix to reach a resultant temperature before being pulled into the oil pump. Anyone know the exact location of the oil temp sensor? Maybe it's located in an area where there is hotter oil?

Yes. Look it up in the service manual and you'll know too.
