Re: recommended oil weight
I have an opinion about motor oil, changing it frequently is more important than brand or viscosity. A few years back my employer gave me a 96 jeep with 100,000 miles. I went to my friends place for an oil change. He put in a Napa filter and 10w30 Napa oil. I didn't much like that. At 200,000 miles he was still putting in a Napa filter and Napa oil. When I turned it in, it had 250,000 mile with, you guessed it. I changed oil every 3,000 miles and the valve cover was never off of that engine. The last time I ask one of the company mechanics he said the Jeep now had 350,000. I am not promoting Napa oil or filter, but the concept of regular changes.
