Actually, switched to 20/50 in December after the first 2800 miles, and I didn't drive much during the winter anyway, so I'm not real sure how much it affected the situation. I'm pretty good about letting it idle until warm. My
oil pressure is about 80-85 lbs cold, about 70-75lbs warmed up.
I'm certainly not the only one to have used 50w racing
oil on a roller cammed motor. If the bronze gears are that sensitive to
oil weight, then they are a POS setup in my book.
