oil for high mileage vette
Have almost 150k on mine and am running castrol gtx 10w40. Oil pressure gets into the low 20's when idling when 95 degrees here. I have the parts on order to get the stock temp down a bit, but would like to use a thicker oil to get the pressure a bit higher. Any suggestions?

What's the pressure from say 1500 RPMs up?
What's the oil temp at idle?
From what I have read here, 20 at idle isn't unusual, but, like you, I would be a little nervous
I have run a 20-50 synthetic for the last 25000 miles, near 100000 now and my pressure is around 50 at hot idle and 65 plus at speed.

Mike, I'm use the Castrol "high mileage" 20W50 oil in my 158,700 mile '88.
After everything is warmed up, I run about 40lbs at idle and 60-70lbs. pressure cruisin' at around 75mph @ 1700 rpm. I burn maybe 1/2qt of oil between 3000 miles changes. I can live with that.

Re: oil for high mileage vette (fixvet)
cool dudes:) thanks for the advice. I have always used castrol products since my 77 trans am days (400ci headers torker high rise-650 dfdp holley, fairbanks full race tranny-ported and polished heads )so will probably stick with that. Pressure comes up to low 40's at 1500 rpm .
