Right, Rislone did the job, but so would MMO or a host of other products, provided they contained either solvent or very thin oil or both. The VVT mechanism really wasn't carboned up - it was gummed up - possibly from using oil of too heavy weight, or maybe just drivng the vehicle around town, and not enough highway miles.

Toyotas (and a lot of other VVT vehicles) suffer from this same syndrome (even with oil as heavy as 10w-30). I've seen Toyota oil pressure lights come on (which really gets some attention!) simply because the oil pressure is low (or non-existent) somewhere north of the VVT mechanism. The engine (not counting the VVT) is actually running just fine. There's an odd message on this board from a user who states that he lost oil pressure because of adding L-M MoS2, which somehow clogged his oil filter - an almost impossible scenario. To a certainty, his oil pressure was fine but his oil pressure light came on because his oil weight was too heavy or his VVT engine was otherwise gummed up - all totally unrelated to any oil additive.

Rislone is fine - this is not intended to criticize the product - but it is hardly unique. Modern Japanese engines like very thin oil - the thinner the better.


I don't think the VVT valve was carboned up either (that was the mechanic's explanation and I think it was a general explanation). I think it was sticking from either thick varnish or a piece of gummy sludge or both. The oil weight is not in question since I run a 5W30 full synthetic the year round. I do think I will do occasional "Italian Tuneups" and make some longer trips in it just to make sure it gets to max temp.

Quote:
Which is to say, it's a lot like MMO (without the fragrance and red color).


I would have to disagree here.

The Rislone product contains no light hydrocarbon solvents. It does contains a detergent/dispersant chemistry similar to Pennzoil's, an ester, a friction modifier, an AW agent, and testing did show it was a 5W20 weight.

16 oz. of a 5W20 in a 5.5L capacity sump would only reduce the viscosity about 0.5 cSt at the most.

Whether or not MMO would have have the same effect, who knows, but this mechanic has 35 years of experience with all makes of vehicles, and when you're in a pinch, you take the best advice advice you can get and run with it. smile

Just to be clear, this was the Rislone Engine oil treatment, Part Number 100QR seen at

Rislone EOS

and not the engine oil supplement with zinc treatment.

Again, I am not a fan of any third party engine oil additive but this one did solve a problem.


It sounds like something worth trying. I am not a big fan of oil additives either but I believe they do have their place in certain situations as you say.
Cant beat the price thats for sure. Thanks for the info!


I'd give it a shot too.

From their site they say this:

Bar's Products, Inc. announced it's purchase of the Shaler Company and Rislone name brand in May of 2006. The goal was to maintain the integrity of the original Rislone formula while updating the overall look of the products you see in stores today.

Here's a product from 1921 that still works, if the above info is still correct. When you have something good no point in changing it.

If it works and it costs something like 5 bucks why not use it?

Update -

Finally got the oil changed yesterday. It was pretty dirty after about 3500 miles. I decided to go with Maxlife HM 10w30 synth blend. It's a 6 quart crankcase, put in 5 quarts oil, 1 quart MMO.
I'll keep an extra quart of Maxlife HM 10w30 in the car and check it every so often. I decided to use a slightly thicker oil, but not too much, to start with. From my experience with troubleshooting in any arena, I've found that not changing too much too quickly is often better. Small adjustments.

I'm going to run a short OCI, 2500 miles at the most, do another 1 quart MMO next oil change, then probably switch to a full synthetic oil.

Sounds like a good plan. You could go to 3,000 miles for your cleanup if you'd like.

I think what MolaKule is saying is that a person should not put something like Techron that contains PEA into the motor oil. But a product like Techron with PEA is designed to be used in the gasoline for cleaning and combustion. PEA is already used as an additive in gasolines.

There is a difference.

My favorite combo as well (15w40 HDEO plus MMO). Currently running an OCI's worth of Delo/MMO in the Lumina, it is crudded up after years of coolant contamination (now fixed).

So I just noticed an issue yesterday. My Jeep almost stalled a couple times when idling or going a few miles an hour in stop and go traffic.
I just filled up the gas tank Saturday, and put in the Lucas Oil fuel treatment w/ 23 gallons gas. (Lucas Oil fuel add. is for up to 20 gallons, IIRC.)
About 5 days before I half-filled the tank with no additives.
About 5-7 days before that I had put 8-10 ounces of MMO in the fuel with about 19 gallons gas.
I'm not going to run any fuel additives for at least 3-6 weeks going forward.

A week ago, did oil change, as mentioned a few posts above.
6 quart engine.
5 quarts Valv Maxlife HM 10w30
1 quart MMO
(I normally use Maxlife HM 5w30.)
This OCI and previous have all used the synth blend of Maxlife. Will switch to a full synth after I run the MMO one more OCI.

I've read on here that once in a while fuel or engine treatments can clean things and uncover problems. Any ideas?

I've got to take it into the shop soon as there's a clunking/clicking sound coming from under the front end when I turn or go over bumps. I'll have them look at the stalling issue but I also like to get multiple opinions.

Thanks.

I am a big fan of MMO but IMO running a full quart with a relatively thin 10w30 in the heat of summer leaves you with an oil that is just too thin for best results in the venerable 4.0.

I'd run a quart of it with 10w40 without concern, but since it's summer more likely 15w40.

With a 6 qt sump, 5 qts of MaxLife 10w-30 and 1 qt MMO yields an 8.34 cSt at 100 degrees c according to widman.biz

Am I correct that MMO at 100 degrees is about 2.6+ cSt?

Not familiar with Jeeps but it appears that a lot of owners here lean toward 10w-30 and the MaxLife HM out of the bottle shows a cSt of 10.7. 5w-30 shows the same value at 100 degrees

That 8.34 compared to 10.7 seems pretty light

Thank you for the replies.
1. Could you explain this a little more? Want is cSt?
2. Should I make this a short OCI, and change it again in 1000 miles?
3. Can I mix a thicker Valvoline oil (not Maxlife) by adding a half quart if the oil goes down a little? Based on other threads I've read I'm guessing it doesn't, but I'd like to be sure.

Thank you.
