So I have been using Arx maintenance doses since day one with two brand new motors (Largely to use up the last bottle). Vehicles have 23K and 32K GM 3.8L and 4.8L motors....both motors are now on Mobil 1 oil and using the OLM with highway miles. Previously used Castrol GTX with 4-5K OCI. All is well with motors, but do I need to continue to use Arx maintance doses when running mobil 1 ?

I assume that Mobil 1 will be a cleaning agent as well as an excellent lubricant. Why run Arx any longer ?

Thoughts ?

You could or use Lc20?

I have another family memeber that has been using Amsoil since day/mile (0001). Inside the VC is like brand new. Been using Lc20 for 10 months.

Going to try ARX and see what happens.
 
TonyMazz:

I'm running ARX as a maintenance dose in my I30 with GC-green. I'm also running it in my '05 Highlander with Pennzoil Platinum.

Overkill? Maybe. But with 8-9 month OCIs on the Infiniti, I feel like it's extra insurance.

How many miles do you drive per year? My experience with the OLM (GM) is that it's giving me 8k-9k OCIs, should I choose to do so. At that mileage, I'd be more comfortable with ARX in there, regardless of whether it's a full syn or not.
 
I drive 80% highway miles, and do about 25-30K per year. Live in Wisconsin, like Cinnci it gets cold as well as hot. I similarly have hit 8K-9K OCI with an AC - Delco filters....just started using mobil 1 and will from now on....

How much do you use for a maintenance dose ?
 
vronline - ARX is not an additive here.

Eddie - I agree but using ARX would keep the engine more constant in power and cleanliness. It is either do an ARX every 25K so your power etc will go up when clean then back down where dirty. Then do it all over again when you clean.

Or just keep it clean, constant levels, with ARX or Lc20 in oil all the time.

I have not using ARX long term and only used lc20 in 5 engines I take of for a few oil changes.

For me I am trying to weight the price/application of both for long term use.
 
If you're adding it to your oil, I consider it an additive...

If I'm paying the money for Mobil 1, I trust that it is doing a satisfactory job on is own.

Satisfactory maybe. Better is quite possible with the right product used under the correct circumstances. I've had LC20, for example, cut my insolubles to almost nothing. One of the "Brians" here used ARX in a dirty Saab engine, with obvious visual evidence of good effect in his cut apart filters. You really should look over the info here, especially in the UOA section, before making blanket declarations about additives. Pretty clearly, some are garbage, some work as advertised. Sometimes there's no benefit in using a certain additive, sometimes there is.

I thought the same way but ARX does not change the properties of the oil. That is per Frank.

I have used Amsoil for years and also thought the same as you did.

I also agree. From the last oil test Lc20 cut down all my wears etc from 50% and over. It is amazing what it does.
 
I'm with the side of there's no need for ARX if you're using M1 full syn. That stuff will keep your engine as clean as a whistle.
 
Tony, You really should not need to!! Mobil-1 will usaly keep most engines really clean inside. I would maybe use 16 onces of LC20 once every 2-3 years as a flush or use Auto-Rx every 36,000-70,000 miles. This is only if you want an engine so clean inside it looks like it just rolled off the assembly line.

Is that all I am, one of "the Brian's..."

Yeah, I had some dirty filters and a decent amount of crud removed. It wasn't spotless by any means but it was doing something. M1 may do it by itself but take years longer if you're talking about cleaning an engine. If you're talking about keeping an engine clean.....that's a different story and dont have the info to tell you one way or another....
 
Go to the additives forum and look at some of my and other postings regarding AUTO-RX maintenance dose. I would personally use it as it cuts down on wear and keeps the engine clean. My theory: why go through a full clean and rinse phase if I can keep it clean with a maintenance dose. Whether you decide to go the AUTO-RX or LC route is up to you, both did wonders on my engines.
 
Yup, sorry, just another Brian. . .

(and to be fair, I guess I'm just another ek).

My theory, and it's just that, a theory, is that beyond a certain point, you're absolutely right. OTOH, I think that if caught early, and addressed aggressively, I do think an engine can be returned to a "clean" state.
