    Ram 6.4 oil sampling problem.

    An Update: Recall that I was never able to obtain any oil samples from my wife's Chry 300 because for some reason the 1/4" OD tubing that comes with my sample pump will NOT fit past the bottom end of her Chrysler HO 3.5L SOHC V6's dipstick sheath and into its oil sump. There is some type of...

    Maybe this comes out bigger?? Thanx for bringing the legibility / size issue to my attention! ["I feel your pain wondering about your sample's integrity, but since the boron and molybdenum levels are inline with an Amsoil Signature Series oil, I'd lean toward the sample was legitimately from...

    An update: I was NOT ever able to convince my 1/4" OD oil sampling tube to fit down into the sump of my wife's 08 Chry 300 3.5L SOHC HO V6. But as mentioned previously, her car went in for some suspension work & the techs extracted an oil sample from her drainplug at that time. Again, don't...

    Ewww! But in LA, this behavior wouldn't surprise me!

    I've got the pump; its tube is 1/4" OD. It fits into the dipstick sheath, but stops about 3" shorter than the length of the dipstick (i.e.: sample tube fits down the dipstick tube, but not all the way in to the oil sump. Confounding! Other threads have expressed success with 3/16" tube, but...

    Thank you! Your final thought is what has captured my attention. At the time the rocker work was performed, (Jan '25) her car was running whatever oil the Dodge shop she usually takes it to uses. Here in the greater Lost Angeles area, there are 2 major "CDJR" shops: Glendale & Canoga. Canoga...

    This is hardcore, and I appreciate where you're going with it. I like it because it's sensible and pragmatic, nonetheless, it's imprudent for me to execute. If possible, I'm going to get a sample myself (using a smaller diameter pump tube) this weekend. If that fails, (& until it succeeds, I...

    That's why I'm 'itchy' to get the advised 2K miles sample. We park our cars in the same pessimistic, over-thinking, assuming-the-worst garage. If the Al drops in it, I'll back way off; till then: 🥵😱😡🤬

    Thank you for responding!!! I would be happy to post a copy of the Blackstone report, but I will first have to figure out how to sanitize the personal info out of it before I post. What is "Valvoline Restote & Protect"? Could be a typo in there (I'm guilty of 'em too) but I'm not aware of the...

    Hi & thanx for caring to respond! We provide the Amsoil to our dealerships. The dealerships physically perform the oil changes because we are not able to perform them ourselves. We both use the dealer for service because at least they have access to the Factory Service Manuals (or they...

    Excessive aluminum in a recent oil sample MIGHT indicate something less concerning than failing bearings or piston wear...

    Ram 6.4 oil sampling problem.

    I have the same problem as the OP. Not on my 4Rnr; I can draw samples out of it perfectly. Problem is with my wife's '08 300 Touring. Engine is the Chrysler 3.5L SOHC HO V6 (EGG). I put the 1/4" tube down the dipstick tube, but it "bottoms out" about 3" shorter than the length of the...

    Best oil for a 3rd gen 4Rnr w/261k on it?

    Ahh yes, the dreaded pink milkshake is another Achilles Heel, good deal! You may already know these also, but consider a new water pump & front seals, since they're stripping the front all the way down to the timing belt. Also keep an eye on the lower ball joints; failure there can be sudden and...

    Best oil for a 3rd gen 4Rnr w/261k on it?

    9 months in PA after its life in CA? I would encourage checking your box frame for any rust. A bit of surface rust in some places is normal after 20+ years. But though our trucks are pretty bulletproof in many respects, there are a few Achilles Heels to watch out for. One of those...

    Best oil for a 3rd gen 4Rnr w/261k on it?

    I have always run 20W-50 in every vehicle I've ever owned b/c I erroneously believed that heavier oil was a better way to lubricate all motors and I wanted to take the best care of my cars that I could so that (hopefully) my cars would take good care of me. My 4Rnr's seals didn't leak when I got...

    Best oil for a 3rd gen 4Rnr w/261k on it?

    In case anyone may be interested, I sent the following product inquiry to Amsoil over the weekend: "Looked @ your High Mileage products then tried to 'compare' with your other formulations. A 'table' pops up with your products listed in columns and their qualities by rows. There are checkmarks...

    Best oil for a 3rd gen 4Rnr w/261k on it?

    Yeah, I concur; definitely thinking there's carbon & varnish in there and am itchy to get a borescope in the combustion chamber to look @ the fuel side. [BTW: does anyone know about "steam cleaning" your CCs...

    Best oil for a 3rd gen 4Rnr w/261k on it?

    Since my OP, been looking around for oil online. Each company obviously had their own site composed of 'slick' marketing (pun not really intended), and I found the Amsoil site. Looked @ their HM formulations then tried to 'compare' with their other formulations. A 'table' popped up with their...
