Used Oil Analysis - Just bragging

    Just thought I'd do a little bragging.
    I bought my 04 2500HD in November of 2008 with about 30,000 miles on it. I just turned 70,000.
    I sent an oil sample to Blackstone last month just to see how she's looking.

    That's a great report card. You should post some key steps with corresponding dates/mileage you took (or previous owner if you have those records) to receive this kind of good news. Also, I'm just curious, how much does did the analysis cost?

    what type of oil have you been running?

    I really don't do anything special. Change the oil when the message system tells me to (usually) which is about every 7,200 miles. The last change, which was the longest I have ever gone, was approximately 9,200 miles. It was not by plan, it was just too darn cold to do it and the truck is too long to fit in my garage.
    I have used Mobil 1 5w30 and an AC Delco filter since the day I bought it. I average about 11,000 miles a year with 60% highway and 40% around town. Beginning last year, from April thru September (ish) I pull a 5,000lb pontoon to the lake as many weekends as I can. ...and I NEVER "drive it like you stole it"! Like I said, nothing special. Blackstone charges $25 for the standard test and an additional $10 to measure the additives remaining. So it cost me $35 to find out the internal condition of my engine. Money well spent in my opinion. I will probably have it done again in 20,000 ~ 30,000 miles. I am going to do a trans service this spring and will be sending a sample in just to see what up.

    Been running Mobil 1 since I bought my first decent car in 1990.

    If you change your oil regularly and use a quality oil why did you send the oil in for analysis? Where I work at we send samples in quarterly to test the oil to see if it needs changing. Our machines run 24/7/365. Is there really a benefit in an analysis?

    Interesting...thanks for the additional info!!

    Without sampling once in a while, let's say every 30,000 miles, how do you really know the internal condition of your engine? Just because you use a quality oil and change it regularly doesn't mean you won't have premature failure of a bearing or a camshaft that wasn't properly hardened from the factory. Both of which happen and would be detected by an oil analysis. Also, the computer in my truck recommends an oil change at about 7,200 miles. Based on the oil analysis I can extend that to about 11,000. That saves me money and time. So I get peace of mind and fewer oil changes over the life of the vehicle. That's my benefit.

    I was unaware that such info could be gathered from the oil. Thank you for educating me on this. I will have to look into doing this for my truck.

    You have an oil change schedule that shows no wear, why change it????? Go to 11000 miles and when the oil analysis shows wear the damage is already done. Sounds like a no brainer to me.

    Thanks for the information. I've considered getting an analysis done as well, but that's mostly because it's been going through oil faster than it should and since I'm out of the country for a while, maintenance falls on my wife to get done. She knows how much I love that truck, so I'm sure it'll get done.... probably... I'd just like to see something in print telling me what it looks like.

    Interesting thread. I actually didn't know that you could send a sample of your used motor oil and get an analysis done on your engine. It makes sense though, as in my head (for instance) if you had a piston w/bad rings on it, you could detect blow-by on them because there would be evidence left in your oil.. Nice. It's interesting to hear that some Chevy owners are actually going by the oil change % meter on the dash too... because I never have. Its 3,000 - 3,500 miles MAX on my oil changes with Pennzoil 5-30 (its what i've ran in every car/motor i've ever built). But I rarely baby Truck Norris.. I let him stretch his legs and flex muscles quite often.

    ..good thread.. thanks for sharing! :sign0021:

    I am definately going to look into this!

    I change the oil strictly by the owners manual. 4,500 or 5,000 for the Camaro I remember that off the top of my head (I'm around 3500 from my last oil change I think). I can't find the sheet where I put down when I changed the oil last in the Burb though so I may go ahead and change it before I leave for Fort Knox in April. Interesting stuff though. I may have to look into that with 250k on the clock before I do my TPI conversion.

    I'm definately going to look into this. I run Amsoil with their performance filter which says it can stand up to 24,000 miles or one year. Meaning I only have to change my oil about every 9 months because I average 30,000 a year. I wasn't too hot on the idea of waiting that long so I usually change it every six months, once in the spring and once in the fall. It'd be nice to know if the oil is actually holding up to its reputation.

    I am planning a trans fluid and filter change in the next 30-60 days. I will be sending in a sample of the trans fluid too. I only have 70,000 miles on the truck but it is eight years old now.
    My wife's Benz recommends trans service every 36,000 ($370 from an independant MB shop - $470 from the dealer) and it uses 100% synthetic fluid just like my truck. I imagine her close ratio 7 speed is a lot harder on the fluid than my not so close ratio 4 speed.

    Hi, paracutin:

    That is a great idea to post your analysis. I have been doing oil analyses on all my four and two wheeled vehicles for several years now. Nothing unusual in any of them. I mostly run Amsoil.

    I sent a sample from my Infiniti that had 7,000 miles on it (Amsoil 00-30 oil), and it came back with a report that told me I could continue to use the oil in the motor. Dinosaur oil with about 4,000 miles on it from my truck, after a hard trip of towing, also came back with that report. I think it was Valvoline 10-30 in the gallon jugs.

    The oil samples are sent to a lab in Spokane, WA, about a four hour drive from here. I think this is a GREAT thing to do periodically if you are serious about monitoring your motor or gear case for signs of wear or other trouble. Mine have a few more things on the reports, but if you can find a lab that will send you the kits, it is worth your time and money.

    Or if you buy Amsoil from a distributor, they likely have the kits prepaid to send to a lab.

    Ah, but the Amsoil prepaid kits are sent to Oil Analyzers of Superior, WI which is owned wholly or in part by Amsoil. I know this is gonna cause a flurry of flames from the Amsoil guys (personally, I have NOTHING against Amsoil) but I would rather send my samples to an independent lab for analysis.

    Where I live the lab is independent.

    And I am an Amsoil dealer (I don't actively sell for them, I just buy for personal use due to so many vehicles that use oil), but I agree that I would not want to send the sample to the Amsoil owned lab for analysis. Even if they are honest, it has the appearance of bias.

    Exactly what I was trying to say. You were much more eloquent than I.
