Just about anybody's Type F will work fine. We use Royal Purple synthetic in ours. The rest of these guys are right about putting the sensor in the pan though. And for a cooler............. B&M Hi-Tek Super Cooler with built in fan and 175 degree thermostat. Used it on everything from 302/C4 cars to 512/Powerglide cars. Never failed us.
Thanks for the tips. I just installed the sensor in the pan. I also just installed a cooler with fan very similar to the one above. Got it all plumbed tonight. Hope to get it wired tomorrow night. I hope to try it out this weekend. I will let you know the results. Thanks again for everyone's input on this. :Handshake
