RLI Biosyn 5W40 2007 Subaru STi (dyson analysis)

[flatfour562]

AFAIK, antiseize does not contain lead. What brand did you use? [/quote]

Permatex.. I read the msds and it doesn't contained any lead.
Terry thinks the lead is from the fuel additive although the bottle claims its unleaded.

Is TAN correct at 0.24? That's lower than the VOA of RLI 5W40.


I have a map made using the race fuel accelerator. Made around 30 more whp.

Yes that is correct.

I added 1/4 quart during the 2nd oci.

Flatfour,

Was the fuel that you put the accelerator in street fuel, or was it bought at a track? I've seen lead contamination in supposedly unleaded fuel at a track before.

 

[flatfour562]

Yeah I added a whole 32 oz can to Chevron 91 octane.

Maybe unleaded does not mean zero lead??? Analagous to how "trans fat free" in packaged and fast foods does not mean zero trans fat, it means trans fat below a certain level.

I think almost every Torco user that does a used oil analysis has high lead. Decaffeinated coffee does not contain zero caffeine.

Wrong. I've been using Torco (15oz per 12 gallons) for 9000 miles. Here are 4 analysis during that time period and they do not show high lead.

FWIW, I have a 5 gallon can of torco. Here is a picture:

Now I can change that to "or maganese".

It seems as though the copper increased dramatically over your first sample of Biosyn, or am I missing something? I've got a fuel dilution problem and high copper with my H6 Subaru. I'm planning to use Biosyn next change to see if that will help, but it seems like copper wear was even worse in your case, even though fuel dilution is down.

Harrydog,

Copper is an additive with BioSyn. The way it shows up in used oil analysis is rather funky. Terry Dyson had to have some conversations with Bill at Renewable Lubricants to better understand the copper and antimony chemistry.

Yes, it does. Overrun (revs with no throttle) causes unmitigated vacuum in the combustion chambers, which sucks oil past the rings. How much, of course, depends on the oil (viscosity, flash point, volatility, etc.) and your rings.

 

[flatfour562]

Got the Torco unleaded race fuel accelerator tested. Is has a little bit of lead in it.

 

[SubLGT]

With the amount of Torco you used (64 oz), that amount of lead would only end up being around 6-7ppm in your crankcase, and that assumes all of the Torco lead ends up in the crankcase. With your last UOA showing 70ppm lead, I would think you are headed for new rod bearings. But then again, your tin is zero.

 

[MolaKule]

Why do use the TOrco fuel additive? Is your engine pinging or do you get spark knock?

We use virgin 110 octane no lead and do just fine.
