Mobil 1 5W30, 10,000 miles Ranger 4.0 sohc

[rubydist]

Here is the latest analysis on the supercharged Ranger. I dropped to 10k miles only because I have been driving the Ranger a little less (business is down and I've been driving one of the SHOs more), and the 6 months were up. I had located and apparently stopped a few small intake leaks, which I believe is the reason for the drop in wear metals that they refer to.

I changed to M1 0W30 this time, to see if it changes anything. So far, I do notice its not nearly as stiff when cold, and mileage 'may' be slightly up, but not enough miles to confirm that just yet.

Looks good. Vis. is a tad low but still 30wt. Maybe the Al will drop further that you found the small intake leaks.

Time to change the oil. Mobil 1 is not cutting it in this engine. Iron level of 32 is high for BITOG standards. I'd look into PP/ML/Amsoil/Valv SynP...anything but M1.

3.2 ppm per 1,000 miles of Fe is only a big deal at BITOG. This truck IS supercharged and running an extended drain interval so I really don't see how the most current UOA values represent any major issues. I don't believe that Blackwell has universal averages for this type of situation at 10,000 miles either. My question is about the Silicon. You stated that you changed to Mobil 1 this time...what were you running before? The additive levels look pretty similar for the last few UOA's.

Aluminum and copper <1 ppm per 1,000 is a good place to keep them. Good job taking care of the intake leaks I'm sure that helped too! How many PSI of boost are you running on the 4.0?? Did you do any internal mods before adding the SC? Upgrade to larger injectors? Oh yeah one more question...can you keep tires on it as your flogging the stop lights??? Wheel hop can be a mofo with those trucks!! You might be a good candidate for giving SSO a try.

deven, I am not the least bit concerned about 32 ppm of iron after 10-12k miles. (M1 always shows higher iron values, and I've never heard of anyone with a dead engine attributed to M1.)

pickled, I have had M1 5W30 in this engine since 10k miles, I just switched to M1 0W30 this change.

Max boost is 6 psi, stock internals and stock injectors. Keep in mind that here at 6000' elevation, I'm de-tuned by almost 20% due to the lack of oxygen... real atmospheric pressure is around 12.5 psi v. 14.7 at sea level. I'm too cheap to burn up tires, so no big black marks on the streets from me I am adding some traction bars, though, the spring wrap is quite severe.

I think this UOA looks great for a Super Charged application going 10K on 5W30!!!!!I think the K&N or whatever non-paper filter you are useing is letting in too much dirt though!Try their 5W40 or at the least their High Milage 10W30! I think you will get even better results. Wrap that airfilter with a foam pre-charger and watch the tin and cromium drop to nothing!

As to burning rubber I find that I was more consistent with cold tires. Consistency is the name of the game and you just cannot heat the tires evenly to the same temp time and time again plus buy the time you stage it is anyones guess what the tires are reading?

What type of a blower is on the ranger?

What does it make on the rollers?

Interesting truck, got any pics?

 

[rubydist]

Justin, it has a M90 from a 94 SuperCoupe. It made 251 lb-ft and 218 rwhp with an early tune and the stock (3.27") pulley. Now it has a much better tune and a 2.8" pulley, so its better

Here are a couple of photos:

John, I'm using the stock paper filter (Fram) with a modified airbox to increase the inlet size. I might try the foam prefilter idea, though, as I think we have a lot of that fine dust here that might be getting through the filter.

 

[JohnBrowning]

If you use a foam prefilter heck you could use a drop in K&N with the foam pre-filters they sell and not sacrifice filtering but enhance flow!

I think the Fe could be improved upon. TBN retention looks good. (Thank the healthy dose of Ca for helping with that.) Somewhere though, protection is being compromised.

I completely agree. I do wonder if there is a bit of leakage of antifreeze in there with the higher sodium which is also bringing up the iron. I think the iron is elsewhere (not from the cylinder) as the cr. is only 1 after 10K miles.

As someone said this analysis would only be a problem on BITOG
