Here is the report back on my 1st run with G-Oil 5w30. Oil was run for 4 months and 5,000 miles. Vehicle is 2005 Ford Explorer 4.0 w/74,000 miles. Oil Filter was Motorcraft FL820S.

I also have had a Spectre Air Filter in there for 2 years. This is the same as a K&N. So this UOA disproves the fact that an oiled cotton air filter will let in copious amounts of dirt.
 
Is G-Oil synthetic ? If it is, then it isn't as good as other brand name syn oils. TBN downs to 1.8 after only 5k miles is not better than dino.
 
viscosity alert! holy cow below 8 from a 5w30??

does the 4.0 SOHC normally shear oils that badly? if not then I would steer away from this oil personally. that is BAD shear in 5000 miles.

It's interesting how the same oil can perform differently in different vehicles. In this Explorer, it did an adequate job, while the Volvo UOA linked above, it did an excellent job.


No it isn't interesting. It should be expected that an oil responds differently to an entirely different environment.
 
Hate to say it, but not great results.

TBN and visc. are completely and utterly shot in 5k.

For a full synthetic? Not something to be proud of!

....and yes, I'm aware this is just 1 report - it looked good in the other UOA, and this one may be a fluke.

Are you running it again?
 
Yes, I am running it again for 6k.

I'd take one blackstone UOA lightly.
Its alot more accurate to have 2-3 and average them(if applicable)


Where is the VOA of this oil? I've only seen the "Racing" version VOA on here.

I also changed all to "some of"

as all was generic and incorrect.

Thank you for the link... I didn't doubt its existence but somehow I missed when it was posted.

Moly appears to be about the same as the VOA as does zinc/phosphorus. Calcium is a bit lower here though. I wouldn't call the differences substantial. Don't understand boron.
 
More iron than I'm comfortable with, but that could be the engine. For FAR oil it's OK.

Based on the lower viscosity I lean towards this for my two 5-qt jugs:

1. A winter oil in my 5w-30 car
2. A warm weather oil in my 0w-20 car

What do you think of those ideas?

Group V and 6K max for this engine...I am not impressed either, hope more UOA's are coming our way.
