Question Effect of radiant heat on oil temp sender

I've had an Autometer oil temperature gauge/sender installed for quite some time now. I keep an eye on oil temps out of curiosity just to see how they're doing. I installed the sender just above the oil fiter, like the pic here:

I noticed after I installed it that the sender is pretty close to one of the header primaries (actually, it is in close proximity to most of them on the driver's side), but I was never too worried about the radiant heat or its effects on the readings.

Over the weekend, I was out screwing around as I'm known to do, and as I'm driving like an *** on some back country roads, I blipped the throttle to drop it down into 2nd for an upcoming 90* corner. Out of the corner of my eye, I noticed on decel that the oil temps spiked about 10-15* over what they were before down shifting, which made me wonder...

So today, I found some fire sleeve (the black kind from DEI) that I had left over from installing my remote slave bleeder line, and had plenty to slip it over the sender, so I figured "eh, what the hell." Went out for a drive, and the oil temps were oddly very steady...WOT blasts were enough to bring the oil temps up in a hurry, but deceleration seemed to have little to no effect on the temps. Overall, it seemed to help make the readings more steady.

I found some info posted here from 2007:

...but didn't really see any other information on the subject. Anyone else messed around with something like this?

Yes, I have one in the same place. The header radiant heat does effect the reading. What you've done to correct it is the same as what I have done. BTW, I have had nothing but trouble w/ Autometer gauges & no longer use them. Never had one that was accurate. Autometer's response when I contacted them was that Pro racers use 'em. So, they must be good. Pfffffft...never mentioned that the racer's get 'em for free, LOL.

Any recommendation on an accurate gauge? The only issue I've found at this point is that on really cold days, the gauge reads around 160* on start-up, magically goes back down to the minimum reading and starts reading numbers that are believable after that.

I've had good success w/ VDO gauges. Problem I've had w/ Autometer's were that although they were within 10 or 15 degrees of actual temp, they were never actual. Tested w/ radiant gun & stock sensor settings viewed on tuning software.

Also, bought a $17 Faze gauge (cheap) for oil temp & it's spot on. Came w/ sender, adapters, gauge, wiring, lite, everything. So, all I can say is that if you can confirm temp w/ an outside source, in order to double check 'em, there are several gauges that will work.
