1995 993 oil cooler fan modification


Vehicle Information: Model: 993; Year: 1995; Body Type: Cabriolet; Total Mileage: 85000;

Durning my last oil change I used 15/50 mobil one because, I have always used 15/50 on my 1980 and 83 SC. After finding out about 0/40, I now top off with 0/40 mixing the two. I live in Hawaii and it's about 90 degrees. oil presure looks real good about 2 bars on idle, and 5 bars off idle when warm up. Is it ok to mix the two for now, and on the next oil change which oil would you use? It I remember right, on the fresh 15/50 oil change the oil presure when cold would be above 5 bars. The car is eating oil right now (Valve guides) I think, will check for it later.Thank you Hawaii
