what oil brand to you like to use, I have a xj with 157,000 m, year 2000
I will never use Castrol GTX again.
I put some in my '91, and after the oil change, the engine temps ran a little hotter. Now I wasn't overheating, or anything like that, but I was noticing higher temps. I went back and spoke with the manager at Napa, who I know to be a knowledgeable person, and I've had intelligent conversations with before. He asked me what oil I was running, and upon learning I had just did an oil change with Castrol, told me about a guy he had a few years back who came in looking for a thermostat. The guy only had 5K on the Jeep, was having cooling problems, and had just done the first oil change with Castrol. After being instructed to change the oil again using a drifferent brand, the cooling issues disapeared.care to elaborate on that?
There is a great thread on oil and additive packages on here if you search for it, this subject has been discussed many times.
