Amsoil flush revisited

[rob-the-oil-nut]

I did some posting and some PM's. Replies were everything from "use it 100% according to instructions and it'll perform as advertised" to "use it as parts cleaner"
I have it, doubt I could sell it, want to use it. Also plan on doing double Auto-RX.
What are your thoughts as to what order to do them in? I'm inclined to do Amsoil flush, then the 2 Auto-RX treatments (both with used oil analysis which will be posted) I don't want ANY of that flush in my extended drain stuff at the end.
To add a new matter, I have a by-pass oil filter. When should it be changed? Before any of the above 3 treatments? After? Both? (replace something designed for annual replacement in a 6 litre engine, used 1 month in a 1.6??)
Thanks MUCH!
Rob

sounds like you have a good plan to me..what type of bypass system do you have? would it be fesible to remove the eliment for the Amsoil flush?

 

[Rebel Rouser]

I've used the Amsoil flush in the past, and I think it's mostly kerosine, a radical solvent based cleaner. Do the AutoRX treatments, and use the Amsoil flush as a "parts cleaner."

I'd contact AutoRX for advice on the by-pass filter.

The Amsoil flush will hurt nothing. It's not radical. Follow the instructions. Many, many people have used Amsoil flush with NO ruined engines, no blown seals.

If you follow your plan or my web plan, both will give you excellent results.

I have a question concering this procedure, if I may.

I have 00' Powerstroke with 93k miles. I have been running a FS2500 bypass system for 6k using Rot 15w40. I am about to change to Amsoil 5w30 HDD in 2k miles and I was told to use the Amsoil flush before doing this. My question is: What effect will the flush have on my bypass system? Will I need to remove it to properly flush, or can I leave it in place? I don't want to shock the system and dislodge a pile of crud from that filter during the flushing.

Any help would be appreciated.

Correct me if I'm wrong, but I don't see any reason why you can't pour in a bottle of Auto-RX, run it 1000 miles and change everything out. Worst case, you could put on a new full flow filter with the Auto-RX. Plus since you can run ARX maintenance with the by-pass you don't have to worry about what is left behind. Just put in the Amsoil, run it a few thousand miles rinse, and then add the 3oz maintenance.

I just poured 3 oz maintenance of ARX in my 8 quart Amsoil dual by-pass system on my F-150 last Friday before I took off for a 150 mile round trip on Saturday.

Are you replying to Oley Mullins, or me?

I have the Amsoil stuff, and I trust Pablo. I have 170,000 + km (100,000 + miles) so I will be doing a double Auto-RX. In what order, though? Amsoil, then the 2 Auto-RX's?

If it makes that little of a difference, try this on for size: The mechanic that installed the filter (10 before him told me to take a hike and hung up on me) will be replacing the filter. Another mechanic wanted to by-pass the by-pass (I'm not making that up) and run straight dead-dino, no additives or anything, to see the effect on the ticking ("noisy lifter") and the like.
So, drain the existing RedLine, take 4 samples (or more. One each from dipstick; for 2 labs. 1 each from drain plug; for 2 labs)
I could get the first guy to by-pass the by-pass while replacing the filter, take it to the second guy, do whatever tests he wants, hook it back up as it is now. Drain 12 oz oil to make room for Auto-RX (

that oil gets used for mower as a cleanser for the engine; it'll be under 50 miles old and will be in the mower only an hour or less)
Do that, sample, then Auto-RX again. Then on to oil for winter.
Sound like a plan?
Can we come to a consensus?
THANKS!

If you run either of those cleaners thru the engine, you must replace both of the filters when you are done and adding new oil. Do not leave them on after the flush, they could be full of contaminates and be at or near their capacity to hold them. I would not install a new bypass before but I would install a new base filter to make room for the flush.

IMO the Amsoil flush would be the best one with the bypass but I have never encountered anyone wanting to flush with a bypass already in place. I just would not do it myself due to the unknown effect of the by-pass and the cleaners.

Oley,

I wouldn't bother using the Amsoil flush in the Powerstroke ...most of these Ci-4 rated diesel oils will keep the engine very clean. I'd put the Series 3000 in and simply do your first full flow filter change after 3000-4000 miles. I'd then change both the full flow and by-pass filter elements after the Series 3000 has been in there for approx 10,000 miles. Following that you can go to a normal filter change interval. Since you have a bypass filter installed you should be able to run your FF filters for 10k miles and the bypass filter for perhaps 20k miles. It is really best to use oil analysis to determine the optimum filter change intervals by tracking the level of insolubles and/or soot. I'd use a filter change schedule that will keep the soot levels stabilized at or below 1.5% ....That will minimize your cylinder and piston ring wear.

If you generate some oil analysis data with this setup, I'd be glad to look at it and make a recommendation.

This is a 1.6 litre DOHC. Engine itself is 11 years old, but it got 2 new pistons and a whole new head about 2 years ago.
I want it to be VERY clean.
The by-pass element is for Diesels up to 6 litres, up to 1 year. This car is gasoline and it's 10 months.
Should I replace the bypass filter element, do the flush and double Auto-RX and then replace the filter element AGAIN?
Thanks
Rob

People have used ATF in the crankcase with very positive results as well...

Now, I know nothing about this Amsoil flush, and it being an Amsoil product, it's probably very good, but that whole kind of engine flush can cause problems.

I perfer not to use an engine flush unless the motor is so gunked up that it won't even run.

I am doing a ARX flush on my car right now...I have a Gulf Coast Bypass...I just changed the oil( sampled for test) added 5 quarts of cheap Shell oil ( 4.99 for 1 gallon) added ARX and ran 1500 miles or so and am now rinseing with Pennzoil Long life ...I changed both filters both times. (then again my Bypass filter cost .99 compared to your 20.00$$ )
