Hey everyone, new member here who has been doing a ton of reading on this site. I recently ran my 174000 mile supercharged 3.8 GTP with a switch from QSUD to Synpower and a Purolator Synthetic oil filter for 8000 miles at which I finally gave in and changed it due to the color and fear. LOL! The OLM in the car was still reading 25%.
This was all cold winter driving in Canada, though about 85% highway. Note, 1 full litre was added between OCI. I normally use premium fuel and don't baby this car either as I like using the power often.
I had a first time UOA, tested by Fluidlife, a Canadian lab and find the results rather difficult to believe considering the high mileage on the engine and the length of the OCI. Evidently, I can easily go by the OLM at 0%.
I was looking for some feedback as I'm thinking it may be wrong to compare results to what is seen from Blackstone Labs.
Results:
V40C = 59.1
V100C = 10.13
Visc Indx = 160
TBN = 5.5
Fuel = 0
Glycol = 0
Additive Metals
Calcium = 1980
Magnesium = 10
Zinc = 819
Phosph = 723
Moly = 24
Barium = 0
Antimony = 0
Boron = 18
Lithium = 0
Contaminent Metals
Silicon = 14
Sodium = 301
Pot = 2
Wear Metals
Iron = 18
Copper = 12
Lead = 1
Chrom = 2
Alum = 2
Tin = 1
Nickel = 0
Titan = 0
Silver = 0
Vanad = 0
Looks far too good to believe for a high miler. A TBN of 5.5 after 8000 mi?! I've since switched to Mobil 1 5w30/M1 filter (M1 is always on sale around here, I plan to stick with it) and will likely send it's results to Blackstone.
