Torco T4MXR 9 hours in a racing Raptor 700

[ccdhowell]

I VOA for this oil wasn't impressive at all, but since it was already in the engine and sometimes there are good things in an oil that don't show up on a VOA I decided to leave it in and check it. This sample was in for only 6 hours and sheared to a 5w30, but still protected quite well. I used this oil for one practice day; I beat on it quite hard, bounced off the rev limiter all day and banged the gears more times that I care to remember, in other words a really abusive 6 hours...and the Torco didn't do too badly at all. I had an issue with a cheap EFI controller that was dumping too much fuel and have since replaced with a good controller so I'm expecting the fuel issue to get better and hopefully the viscosity won't take such a pounding.

Anyway, here's an example of "the VOA doesn't show an oil's true potential."

Yes it sheared down to a 30wt in part due to fuel dilution but we have no idea if it's a 5W-30 as Blackstone has claimed. It could still be a 15W oil for all we know.
If a 40C vis was taken then we'd have more of an idea although I doubt this is of any import to the OP.

rule #1, don't read their text.

rule #2, don't read the stoners text.

rule #3, if all else fails, see rules 1 and 2.

alum is a typical value
iron is high
copper is borderline high
lead is high unless you have used a leaded fuel recently
manganeese is very high and odd if not in a voa
silicon is still high, get better air filtration.
2% is high fuel, but is not all of that low 58.8 reading.
realize that at 56.8 you are a 20wt. so, this oil is almost a 20wt!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! fuel diluted.

fix your fuel.
get some filter filters!
and take note that whatever you paid for this oil, was toast in 6hrs.

Yeah, I ran this oil for a while and moved to greener pastures. It just wasn't worth the price I was paying for it.
