This is a UOA on the Platinum 5w40. Actually it is a mix of 2qts 5w40, and 2.7qts 10w30, as the store only had the 2qts. I wanted to see if this Euro oil would help out in consumption/protection compared to just the 10w30 viscosity.
This isn't your ordinary LGT, it has been heavily modified to the tune of 415bhp/425trq. It also has a 50/50 methanol injection. The car is dail driven about 90 miles, mostly highway. It does see full throttle about everyday, and on this UOA it also saw about 20-25 dyno pulls, to dial in the upgraded turbo/injectors & alky injection. Here are the particular's:
Comments from Blackstone:
EDMUND: Based on the higher than average iron (from steel parts sharing the oil) we suggest an oil
change to get iron back in the proper balance to the other wear metals. The rest of the wear metals
read close to universal averages (which are based on a 4570-mile oil run) for this type of engine. We
don't know why it increased suddenly here. It may be due to something operational like hard driving or
racing. In that case, it will probably decrease next time, but if it doesn't, we'll let you know. Everything
else looks pretty good here at 48,496 total miles.

used a AVO air filter. Cotton gauze type similar to K&N, but not oiled.
From what I see, the 5w40 didn't do as well as I thought it would have. Also, I didn't know that the 5w40 euro was repackaged Helix Ultra until well after putting it in, had I known that, I would have passed.
Well, the car has Gold GC 0w30 in it now, and I have had good results in the past with it, so I guess I'll just stick with it. Unless any of you oil guru's have any other suggestions? Something within the same price class $5-6 qt.
