finally got my oil temp guage in the SS. I'll post some pics if I get a camera. I removed the cig lighter in center console and fitted the LED and printed circuit board of a cyberdyne digital oil temp guage there. It looks sweet, now I just have to cut a piece of black plastic to finish off the console. I've only driven the car 20 miles or so with the guage. From cold start the oil temp lags way behind coolant temp for a while. The coolant guage will run to 200F as usual in about 10-15 minutes, but oil temp will only be 150F or so when engine is fully warmed up. On the way to work, about a 10-15 mile highway drive, oil temp slowly climbed up to 202F, about 1 deg every 10 seconds. And going out to lunch today, starting the car the oil temp had cooled to 120F and didn't go higher than 202F again. I'm curious to find out, after reading the thread about 5w-20 in a b&s lawnmower engine and oil temp, if GM is also retro-recommending 5w-20 oils like Ford is. If so, I think I may try a 5w-20 oil, and it would be interesting to see what oil temp does. Right now, I'm running pennzoil 5w-30. It's due for change next weekend, and will be using supertech 10w30 full-syn. BTW, oil temp sender is on the port above the oil filter, which I understand is where the OEM sender is located on the corvette (same LS1 motor).
