Valvoline MaxLife 5W-30 Rules!!!
I just finished a 3,000 mile use of Valvoline MaxLife 5W-30 in my 1995 PI (194k miles), and the stuff works great! Two big thumbs up. Before changing the oil out, I let the car sit and idle for 30 minutes, and there was zero smoke from the valve seals. I don't know what's in that stuff, but it sure cured my leaky valve seal problem.
The MaxLife 10W-30 worked well also, but I didn't like the delay (however slight) in getting the oil to the top of the engine. Now I have the best of both worlds... quick arrival of oil and no smoke from a bad valve seal.
