Hello,

I am getting ready for a cross country trip. I figure I will change the oil before I go. I am currently using Castrol GTX 10-40. I am a little concerned about oil pressure. The oil pressure gauge reads about 60-70 when I start it up in the morning. It stays about 50-55 as I am driving down the freeway. I don't have a gauge to compare cylinders at the moment. Should I be using something other than what I am using? Any help would greatly be appreciated.

Stick around, this question usually attracts a lot of answers and you will have plenty of information to digest.

While you are waiting, here's a little oil info to keep you busy. It comes from a Ford HP forum, but the basics are all there: https://www.boss302.com/oil.htm
 
I bookmarked Paul's page , but will probably never assimilate it, no matter how many times I read it. My short answer is 20W-50wt. Brand, not so critical as frequency of changes. Now hold on to your hat as this one does generate discussion.
 
Wouldn't ya know these guys would make a liar out of me.
 
Temporary burn out.
It seems like it was about 2 weeks ago that it was hashed out.... .again.
..with ZDDP thrown in for good measure.
 
There's a search feature -- top of the page.
"motor oil" will probably bring up lots of non-related topics. "ZDDP" will bring up all kinds of controversy about lubricants!
 
Hello,

It is mandatory to use 20w50 during summer. Another concern is ZDDP you must add a bottle(Moss) at oil change or use motorcycle oil. I found at W.-M. their motorcycle oil which is SE,SF, indicating SAE specs conforms to our TR6 requirement.

Cheers,

Jean
