yes Pennzoil UP does do pretty well.

That's likely due to some of the additives. M1 is not the greatest formula although M1EP is better, that extra $ gets you the additive M1 should have had in the first place lol BioSyn's BN starts around 10.22 and the active antiwear additives on the FTIR is 35. It is one fucking oil that no...

So Nitration is a huge one, indicates A/F ratios, timing, fueling and additional data using some other values. Oxidation is an indicator of oil temp and how hard the engine is run. Good catch! RLI is one of the hardest oils to read in UOA. It's baselines are so high on everything it's...

I'll give him a call, interested in seeing UOA from a decent lab though

Notice on the fuel %, the improvement on the third sample(BioSyn) second sample was M1 and first sample was valvoline.

I'll post some analysis for you guys to see in a few hours

That oil ended up getting Terry Dyson kicked off Bitog, it's heavily mentioned. Whether an oil is mentioned in Bitog doesn't hold value for me though as the site has now gone to a good joke I heard the other day. Most chevy's today are still on the road(photo of a silverado jacked up with a...

I mean he's got good information and I have nothing against Amsoil, it is good oil, but the case still remains with the fact that Renewable Lubricant's BioSyn out performs the Signiture Series hands down in most engines. I can start to tell by page 5 he must be an Amsoil guy as he only...

Hell yeah it is, where does Troy work? He is spot on with everything he's saying so far, I get the impression he doesn't work in a lab though, I have a funny feeling of how he knows what he knows.

thanks mustang guy, I'm barely at page 3, but already your own guy is saying that a 50 weight will be straining these engines and damage them and even goes to say a 30W is great, even on extended track racing. I agree with this guy on many points he's made so far. He seems to know about FTIR...

Maybe I should rephrase, I am not saying there is no need for 50 weight in certain situations, I have found however that most "racers" are using an oil that is way too thick, if you can get to 275+, again you have some serious issues. That car is being pushed too hard, plain and simple. Install...

email or pm it to me, please. [email protected]

well forced induction 5.0L's are a different story. Can you post one of these UOA's? keebler elf? That's a good one lol

The problem with the heavy oils is they also gum up and the engineers need that oil to flow and flow fast. heavier oils create slow flow, which results in the opposite of what the user intended it to do.

No oil is going to handle that kind of temp, you need to go back and reevalutate the temperatures. You're destroying that oil. Rather than focus on weight, focus on Viscosity Index. A thicker oil is not going to bring down your operating temperature. If you're able to take the oil temp over...

If your engine is getting near 300 degrees, you got huge problems, LOL. Doesn't matter what weight you're running. Running a 5W50 is not going to cool your engine or keep it lubricated. The 40/50 weights are for long track racing. Most of the vehicles I have done analysis run an oil far too...

please point to the thread, I'll pick it apart.

You do realize I have been testing oil for Ford Performance, right? Very very rarely will 5W50 ever be needed in the 5.0L coyote. Running 5W-30 will not hurt the engine but it is a heavier oil, for a daily driver 5W20 suits the engine better. Heavier oils strain components over time, such as...

Driving a 5,000 mile interval and getting back data from the particular oil. Looking at the FTIR analysis of the oil, sheer rates, viscosity indexes, fuel dilution, combustion dynamic, particle counts, analytical ferrographies all stuff Blackstone can not and wouldn't know how to do. Was it a...

A lot of people go to higher weights because they believe it will provide more protection. What they don't get is by going to the higher weights they often create wear prematurely and strain the engine big time. The 5.0L coyote calls for 5W-20 from Ford. If you are tracking this thing and by...
