Hi all,
I'm approaching 3k miles, where I want to do a UOA on the GC that I currently have in my 97 T-bird 4.6L.
So far, in 2100 miles, 1/4 qt. of GC has been used (in spite of the Arx for cars under 100k miles...had 0 consumption with Chevron dino 10/30 with Arx).
I've heard of cars "using" syn.oil immediately after changing over from dino, but that the consumption goes down froem there onwards...
So I wonder...should I use GC again or not?
While the low temp(25-35F) starts have been a little noisier/rougher than with 10/30 dino(I don't know why), operation in warmer temps have been smooth.
This oil is the 1st "normal" batch of oil I have in the car after the Arx treatment; changed to this GC immediately after the ARx rinse with Chevron 10/30 dino: so I don't know if this UOA will really reveal how well this oil does in this engine. But then again, I do want to do the UOA asap, 'cause I'm concerned about my coolant level going down slowly in the cool.reservoir tank..
So I'm battling with the following (?)s:
1) should I use GC again, and hope the consumption goes down with the 2nd run? or should I change to something else?(wish there was a way to know the UOA results BEFORE deciding on the next oil!)
2) should I be more concerned about the uoa values(=do uoa later with 2nd run of GC) or:
about the verification of coolant in oil(=do uoa now!)?
3) this GC being the 1st oil after the ARx: how badly can this fact effect the real values of the UOA?
the car has 93 k miles, btw.
What would you guys do in my place?
Thanks in advance.
