FRPP Extreme Duty Recommendations for 2004 Ford Focus (5W-20)

BACK ON TOPIC!
From another thread QUOTE: MolaKule -
What vicosity would be required at 100C (212F), 5.25 cSt SAE 5-20
125C (257F), 5.25 cSt SAE 30
150C (302F) respectively? 5.25 cSt SAE 40
The above are considered minimum viscosities at the temperature specified as per an SAE/GM paper on minimum lubricant films in engines.
Kind of lends credence to the FRPP advisors recommendations doesnt it?

You gotta like the pumpability of the 0w- weight, and it doesn't seem to be as thick as GC 0w-30.
BTW,for all the 5w-20 bashers: Please stop. Would you use all-season road tires at a track school? No. Would you use stock brakes at an auto cross event? No. Then doesn't it pretty much go hand-in-hand (foot-in-mouth?) that 5w-20 may not be the best choice for such events? No one has ever claimed 5w-20 is the end-all-be-all of motor oils regardless of engine, vehicle, usage, etc. So let's stop interjecting (please forgive me if I spelled this wrong, as I am not perfect either) with negative comments about this oil. We all know not everyone likes 5w-20, just like not everyone likes GM, Ford, DC, etc, etc, etc....

Sorry for peeing you off folks, but terminology is important. You wonder how such great oils have been developed over the years? It's because engineers and scientists have applied scientific principles to the quest for a better product. Imagine if you will if they just decided to rank any improvements in lubrication changes by, "it feels smoother" or "it feels faster". Molakule chimes in with some common facts and you all swoon like he turned water into wine (no disrespect intended). An unknown person who shows up with three science degrees and has worked with jet engines and automobile engines as a professional engineer for 24 years and I'm a "pseudo intellectual". I had a few other engineers private message me with the warning of the beating I would take here, but I ignored them. I guess my faith wasn't so well placed after all.

With the 20wt oils, it is my understanding or thinking that while your loosing some viscosity compared to a 30wt/40wt, you can make up for that by using better additives or more additives. It's clear that 20wt oils are for MPG, but I havn't seen any proof yet that they are in any way bad. In fact, they seem to be out performing their 30wt counterparts. Also you have to remember for daily driving in most modern engines, you can go as low as a 10wt oil if you wanted to. Molekule has stated this before. I wouldn't recommend it but it's possible that maybe the tolerances are that tight. For racing though, I'd clearly use a 30wt/40wt oil.

You are taking this board...and IMO, yourself, way too serious.
BTW. I made the "pseudo intellectual questions and or arguments" remark. Not to disappoint you, but they were not about you.....although a few more posts...... ![[Wink]](images/icons/wink.gif)

BTW when I had the LS1 Corvette I enjoyed your advice on some other boards as well. If I somtimes seem like I argue just to argue.... well I consider it debating. I have found it helps me come to decisions on things. It seems to work for me. If I have offended anyone I apologize. Gene

5w20s are better than regular 5w30s. Even the syn 20 wts(mobil 1 0w20 for example) has a great additive package for it to work well with engines. My uncle has over 105,000 on 20wt oil(2002 ford focus se 5 spd, we all know how many recalls that car had), and his car has no problems(only the fuel pump and alternator were replaced under warranty, which have nothing related to motor oil).
FYI-2002 Focus had zero recalls.
http://www.alldata.com/TSB/021950_en.html
Don't confuse recalls with Service Bulletins. I own a 2002 Focus ZX3 and have run 5W-30 since 6 months after purchase. I took my car in 1 week after i got it (New) and have never had to take it in for recalls or maintenance.
5w-20 is fine for autocrossing *. Half the 20 wt UOA's from the Mazda 6 group are autox particpants, and some are tracking AND going to multiple AutoX schools.
One fellow, Bill Kratz, has a UOA with over 60+ autox runs (3 schools)! And thats in maryland heat and humidity (mid/upper 90's).
Oh ya and he's using 0w-20. (in 3.0 duratec based motor).
Modular blah blah ya. But the 2.3 6i's are showing excellent UOA's as well. 20 or 30 wt. Cept you get better performance outta the 20's, and better gas mileage to boot!
*=In many Ford Based Platforms

Even if the vanadium portion of the alloy doesn't show up, the iron which makes up the majority of the alloy will. Are you saying that there are known examples of engine components wearing rapidly without any evidence of the wear being detectible by a low cost used oil analysis, or are you putting out a red herring?

I learned this info from the Wearcheck site, very informative!

quote:So Exactly which metals/materials aren't read? I believe the basic UOA process involves PQI sceening and use of a FTIR Spectrometer. The spectrometer identifies the type and amount of wear metals and contaminates. Its only limitation is that it can't detect particles larger that 3-5 microns; but it's believed larger particles are only a result of abnormal wear ie.serious mechanical problem. Plus abnormal wear will also cause a spike in small 1-5 micron particles; thats why trending is so important. I'm sure one of the experts can correct and/or elaborate on the above.
UOAs do not tell you the whole story, there are some wear materials that are not reported in your UOAs.
