4 Year Old Engine Oil Change Using AMSOIL Engine Oil Flush

Yes, I should be hiding my head in the sand that I didn't change my 2005 Jeep Liberty motor oil for over four years! I have a partial excuse but I'm still not proud of letting an oil change go so long overdue. My Jeep Liberty went through a string of accidents rendering it un-drivable for some of that time while I worked on swapping out it's bent axle shaft followed by replacing it's entire rear axle assembly. Then, I was forced to start working from home due to COVID-19 restrictions so I literally wasn't driving anywhere at anytime. In face, this Liberty only spent enough time on the road to keep it charged, keep it's seals from drying out and only because I was trying to use it every couple weeks for short drives to keep it running. However, all oil needs to get changed even if it's not driven very much simply due to condensation, oxidation and natural chemical breakdown of it's various additives. All in all, just not a great idea letting it go so long without an oil change.
That's why I trust @AMSOILinc full-synthetic motor oils. Their products are high-quality and formulated for the best outcomes giving me a peace of mind I simply don't get with standard, regular brand motor oils. For added peace of mind, I wanted to try AMSOIL Engine Flush to be sure as much of this old oil was removed upon performing this oil change. What came out sure looked black and it flowed very freely making me consider the strong detergents in the AMSOIL engine flush did their duty. Prior to adding the flush, I actually sampled a small amount of motor oil and sent it for analysis as I was curious how the AMSOIL synthetic motor oil in the Jeep Liberty held up over those four and half years of sitting outside in cold Michigan Winters and humid, hot Michigan Summers rarely being used and when driven it was only for short drives which is a formula for disaster for most cars and trucks. Be sure to stop back and see my upcoming video with the results from the oil analysis to see how bad it was and what damage it might have caused to my Jeep Liberty's 3.7L V6 engine.

I am a big fan of the AMSOIL engine flush before switching over a vehicle to AMSOIL fluids. Great video.

[@WorksIRL]

Ever since doing this AMSOIL engine flush before draining that very old engine oil, I can truly tell my Liberty's V6 has been running like new! I know debunkers will cry foul but I truly try to be objective and I'm telling you, the engine has never run smoother and the power has definitely returned...even my wife commented on it the other day on what's now a nearly 20 year old SUV. Thanks for watching, leaving your supporting comment and best of luck in your continued independent AMSOIL dealer success! 👍

Good point about the transmission. Even reputable technicians will say that you shouldn’t flush a transmission with more than about 65 or 70 thousand miles on it. You’re supposed to just drain and replenish what you drained, which is not all of the fluid in the system.

[@WorksIRL]

My Liberty says to change transmission fluid every 60,000 miles but I got into changing it every 20,000 miles presuming it always leaves a certain amount in the torque converter each time...seems to have done the trick over all these years it shifts like new.

@@DiligentDave1966 that sounds right…I went by fill capacity on my Liberty’s transmission and dropping its pan and letting it drip out all night I think I calculated about 1/3 remained unchanged which is where I came up with changing it every 20k instead of 60k…figured the full amount has been replaced no more than 60k miles.

You can also use Seafoam. That stuff is a mechanic in a bottle. I dump a bottle in my tank about every 4th or 5th fill up. Before I go into get my oil changed I will dump a bottle into the engine and run it on the way there. Maybe 10 minutes, no more. When they drain it, the crap that comes out is amazing. And then I refill with 100% synthetic.

[@WorksIRL]

That stuff has been around forever it seems and the positive results you’ve experienced must be exactly why! Additives and flushes are seemingly polarizing with half swearing by their regular usage and the other half naysaying they’re simply money making snake oils causing more harm than good. I find it hard to argue with results like you’ve had and what I’m seeing thus far with this AMSOIL flush 👍.

I'm sorry to hear AMSOIL has lost you due to their pricing...I think they try to keep it reasonable as they can given the high-quality ingredients and trying to locally-source as much as possible. Glad to hear you trust their flush even with their pricing. Thanks for watching and sharing your thoughts! By the way, I do use their 12k-mile "middle-grade" to cut costs a little from their highest "Signature" 25k-mile oil and to me it doesn't seem that much more than the comparable oils...though, I do pay $16/year to be a "Preferred Customer" but it usually more than saves me that just in lower prices and often free shipping and other "free" deals/discounts, etc.

[@zappatx]

Around $11.50 as a PC case pricing for the top Signature. Not bad at all. Or just under $10 for XL. Penzoil here locally is $13 per quart so Amsoil shipped is the better deal.

[@WorksIRL]

Ugh! That GM 3.6 oil filter location as you’re describing sounds like a scene from “Indiana Jones and Oil Change of Doom”! 🤣 I concur 130k miles isn’t like it was on vehicles of my youth but when trying to stay on-track with OEM oil change maintenance schedule then going 4.5 years in less than favorable conditions that’s a big change allowing mental paranoia if not real potential physical decay. Like so much of these “flushes” it’s likely more mentally soothing than real 😂. Thanks for watching and sharing how much worse my oil filter changes could be 👍.

[@jmackinjersey1]

oil doesn't really break down like you think it does. How do I know this? Because the Military doesn't change their oil on a regular basis. We send the oil samples in and the lab told us when it needed to be changed. It isn't milk that expires. Oil needs to be changed when it is dirty, more or less, when it is full of metallic particles too small for the filter to remove.

Great information to share with us…thank you!! Presuming you’re currently serving or served…THANK YOU FOR YOUR HONORABLE DUTY 🫡🇺🇸

[@jmackinjersey1]

@@WorksIRL Thanks for your support. Yes, oil will break down when being used and abused, but it is mostly discarded when it is full of material that "flakes" off of the interior of the engine that is too small for the filter to hold, or when it gets too hot after heavy use of the engine.

@@josemedeiros007According to AMSOIL.COM website, AMSOIL P.I. Performance Improver Gasoline Additive is $16.69/bottle retail and $12.99/bottle as a Preferred Customer. Again, I think I've gotten bottles for free and/or $5-deals AMSOIL periodically does throughout the year for Preferred Customers which is when I usually pick up a bottle. I've found paying $16/year to be an AMSOIL Preferred Customer more than pays back that annual fee and if I spend $500 on products in any given year they give me a free year's membership. I've been trying to cut back on spending so I haven't hit that amount myself but it's not hard to do if I'm maintaining multiple vehicles. I still have some stock left over I'm using up from when I was an AMSOIL independent dealer so I still have "surplus" since I wasn't a "go-getter" dealer...mainly just did it to get the cheapest "dealer cost" for when my kids were still living at home and I had a "family fleet" of vehicles to maintain🤣.

[@JeepsAndEats]

I wonder if I can use it for my AT that has been sitting for a year. The oil not only lubricants the engine but also the transmission.

[@WorksIRL]

You're right, the bottle is listed for engines and transmissions. However, my hesitation on using in automatic transmission is the fact that unless you actually "flush" out the entire automatic transmission by purpose-built professional transmission servicing equipment or disconnecting the transmission fluid lines to/from a transmission cooler, some of that flush would remain in the torque converter. I've done my own automatic transmission changes by simply dropping the transmission pan and I'd estimate about ⅕ to ¼ of the fluid remains in the torque converter so I'll generally do more-frequent transmission changes like every 20,000 miles if my Jeep calls for changing it every 60,000 miles...that's likely a bit extreme but it seems to have kept the fluid very clean and no transmission issues. So, I decided I'd only use the flush in the engine, not the transmission. If you're doing DIY, you might consider doing the same thing. By the way, I watched and enjoyed your "Jim's" video a few months ago and like your premise of "urban Jeeping"! 💪I've always joked that our roads are so poorly maintained and such horrible condition here in Michigan that you need a 4x4, heavy-duty Jeep just to drive on-road without ever going off-road so I can relate to your bumpy old streets!😆Thanks for watching!

Hi Can i do the engine flush on my 2018 Jeep Grand Cherokee v6 3.6 4x2 with 28k ? Can i use Amsoil Engine Flush ? Then put clan oil Valvoline Extended Protection 0w20 ? Thank you

[@WorksIRL]

Please forgive me dodging your direct questions but all vehicle manufacturers state owners should perform vehicle maintenance according to the manufacturer's vehicle maintenance schedule stated in the vehicle's owner's manual and those usually explicitly state not using any additives or cleaners in the engine. That said, the irony is my local Jeep dealership service department routinely pressures all the owners in their quick-oil change lane to purchase a multitude of various expensive additives and packages from flushes to various additives which is one of the reasons I stopped going to dealerships and perform all my own maintenance. 🤷🏻‍♂ What you do with your Jeep is your decision. I presume AMSOIL has done their research as to their engine flush being safe to use per their stated flush instructions and that's why I felt it was safe to use in my video using it to flush what was some very old oil in my 2005 Jeep Liberty 3.7 V6. In regard to your Jeep Grand Cherokee, again, I'd have to rely on AMSOIL's statements about usage safety but I personally would question whether you really need to use a flush given how relatively new your vehicle still is being a 2018 with only 28k miles on it. To me, that's almost still a brand new vehicle and engine. Presuming it has had its oil changed per the vehicle's recommended schedule and the proper certified oil and viscosity has been used in it. In regard to using 0W20 Extended Protection Valvoline motor oil, I don't have any experience with it as I've used AMSOIL exclusively for well over a decade. As long as that Valvoline 0W20 is the viscosity your 3.6L V6 requires and the motor oil meets Jeep's certification requirement (i.e.: API rating, etc.) then I'd presume it's okay but again, you need to make your own call on these types of decisions. If you read through the comments here, you'll find as many differing opinions about using and not using engine flushes and a myriad of different methods and products for those that say to do a flush but even there you'll find many don't agree doing it on younger vehicles and some say don't do it on older vehicles. The easiest answer is just follow the manufacturer's stated maintenance recommendation. I'm personally inclined to trust AMSOIL and their products because I've used them so long and think my vehicles have operated better than my vehicles used to operate before I started using AMSOIL. Again, sorry for not giving you a direct answer but these vehicles cost us an arm and leg so you really just have to make your own best judgement on how you prefer to maintain them. Good luck and keep us posted what you decide to do! 👍

[@ryanharrison2260]

I would've put a cheap oil and another filter on to flush it again before the amsoil. I did another oil flush with fresh oil just to make sure the engine flush was all out and then I put a slightly thicker oil in for my next oil change.

[@WorksIRL]

That is a prudent process you describe and certainly would be sure all the old oil and flush is flushed and cleaned out. 👍 I've been really impressed even just doing it the way I did in the video with this flush then the oil change...the Liberty has been running like a champ! Super smooth acceleration and far better power...quieter engine, too. I'm sure debunkers would say it's a placebo effect but I've tried really hard to be objective and it's been an amazing performance that I'm really thinking this flush does really work. Thanks for watching and sharing your even more diligent cleaning process ideas. 💪

@@WorksIRL Its not a placebo effect, it works. I did it on my 2012 Subaru STI. I normally put 5W30 in it, but after the flush, I put in 5W40 which is fine, but it has never run better since I did it. It runs smoother.

[@freebehindbars8654]

What about the engine flush in the system that wasn’t evacuated? The only time I’ve flush, on a truck that sat for years, I ran SuperTech through it for a few hundred miles before going to Amsoil. No way it doesn’t adversely affect the oil.

[@WorksIRL]

I had the same thought as it seems only natural that some of the flush remains after draining. I put trust in the AMSOIL engineers following their instructions and I presume it likely means the flush simply contains higher concentrations of ingredients normally found in motor oil already and after draining they must calculate the mixture would be diluted enough with the new oil to not have an appreciable impact. Just my presumptions but I do agree with you that there must be some quantity left behind after draining. Thanks for watching and sharing your insights! 👍

If you are not using the superior oils and filters designed for extended intervals...AND actually testing your oil for feedback...you are misinformed and providing bad advise to others. BMW "says" I can go 10k miles...but my oil lab analysis reports using AMSOIL Euro says 8k-8.5k is safe range (maybe even 9-9.5k) for the additives to still work so I am changing at about 7.5-8k range. AMSOIL Euro is one of the small handful of BMW spec approved oils available. I will flush about every 4th or 5th oil change.

[@WorksIRL]

What you're stating sounds about right based on what I've researched as well. 👍Lots of "old school advice" that's been around since the days of old makes some minds hard to change. I do think part of the issue is engine designs have drastically changed in the past two decades so there's a fair "mixing" of old and new engines where some of those "older engines" user manuals still espouse the tried and true 3k intervals. Combined with relatively inexpensive oil changes many folks figure it's "cheap insurance" playing it safe and changing when there's likely plenty of oil life remaining.
