I screwed up and didn't change my oil as I should. We've been driving our V10 Excursion on a lot of trips and I didn't change the oil for 9600 miles. At 5,000 miles I changed the filter and added a quart of oil. Anyway, I was concerned that what I did resulted in too much engine wear so I took a sample of the oil and got the results noted below. The report stated I could go an additional 900 miles before the next oil change. What do you think? Thanks

Al----------5

TBN was 2.0

Oil was Royal Purple.

 

Silicon, iron and copper seem high; How's your air filter? Air box and ducting all sealed up?

 

furball69, I had 12,000 miles on the air filter at the time of the oil sample. My air filter system is totally stock and I use a Wix filter. The system appears to be in good shape. I'll take a look at it tomorrow evening. Is their something I should pay particular attention to?

 

You didn't say how many miles are on your 2004 V10. I would assume like most folks around Houston, you have better than normal like maybe 35-40,000 miles. The wear metals are certainly within any acceptable level. If you cut the numbers in half it would be close to being what it would be at 5,000 miles. You can also cut the numbers to how many per 1,000 miles. Anyway you want to cut it the RP did a decent job. The TBN at 2.0 is pretty decent for RP as it isn't known as an extended OCI fluid. I only have two concerns. One is the silicon. If you had any work perform on the engine that any type of silicon sealant was used- there's your SI. Otherwise, you are getting more dirt in the engine than I would fell comfy with. I'd give the old engine bay a good look see. Second, you might also want to watch your coolant. While the sodium at 9 is not anything fatal, it indicates either a minor coolant leak or you took a trip down the beach and you have an intake leak of some kind. Nothing to get excited about or worry over, just keep your eyes wide open when looking under the hood. Otherwise, this is among the better UOAs I've seen on RP in a long run. Apparently your V10 likes it and I would suggest staying with it.

 

Flash, I have about 45,000 miles on the Excursion. I have been worried about a coolant problem as I have added coolant (2-3 cups each time) about three times in the last 12-15,000 miles. I'm not sure if that is normal usage because it's easier to see the level in the Ex as compared to my older vehicles. I'm not sure what to do if I do indeed have coolant leaking into the engine. I'm assuming at some point I need to have the head gasket changed but I don't know what parameters I should use to make that decision. Thanks for the help.

 

Did the report include viscosity, flash point, fuel or other parameters? While TBN is just about at the limit, I am a proponent of extended OCI's if you are going to use synthetic, especially in warm climate zones (like Houston). Thanks for posting.

jimandmandy,
yes the
SUS viscosity @ 210F was 55.4,
the flashpoint was 360F,
fuel <0.5%,
antifreeze 0.0%,
water 0.0%,
and insolubles 0.4%.

 

one thing i might add is the new FL-820s filters seem to have a lot of left over silicone dust still on the ADBV i noticed this when i bought 10 at walmart. this could be the silicone you are seeing in the report. when you touch them a light pinkish dust comes off. all of the older filters i have are 100% clean. it could be a bad batch of filters. what filter did you use?

 

The oil filter is a Wix (labeled NAPA Gold) part number 1372.

 

----------------------------
Ford 390, that is interesting. So what you're saying is it looks like a "dust" on the filter? Can you blow on it, and get rid of it? Maybe use a can of compressed air, just to make sure it's removed?
Or, is it harmless in the overall picture and performance of the engine during the oil change interval?

Should an oil filter be rinsed or "pre-flushed" a moment prior to installing it, if this silicone dust is observed?

Just wondering... Ed

 

Seams odd to me that you didn't have any lead in there at all. Even at 40K there should still be some lead coming off the bearings, I would think. I haven't found my reports from my old truck, traded in with about 51K on it. Highest milage of any I have done reports on. Cannot remember if it did or not. With a TBN of 2, that oil needs to go, obviously, you have done it by now. Even a syn like RP will start having problems with keeping acids in check with a TBN below 2. The silicone could be cumulative from all the miles, I would think.

Thoughts?

 

scafes, there will never be any lead shown in spectroscopy in a Triton series engine as there is no lead used in any of the factory components. Any lead that appears on any Triton report comes from an outside source.

 

I found my reports from my 5.4L. I had a reading of 2 for lead. I was not aware of there not being lead in them. Thanks for the info.
