I have a 1999 Jeep Wrangler with a 4.0L 6 cylinder engine. I have been using Castrol GTX High Mileage 10W-30 oil in it. It takes 6 quarts. I was wondering if I can safely use oil which is in an open container I have with the date code K191233 20:03 on it? If so I can buy 5 quarts and combine it.
Also, would it be safe (or better) to use your full synthetic Edge High Mileage product? Can I combine these 2 (5 quarts of the Edge and 1 quart of the GTX)?
The Jeep has about 120K miles on it.
Thanks!
