correct and mineral spirits has been used for years as a engine cleaner when it is disassembled. Most cleaners are certain % mineral spirits.

To be accurate - this is the makeup of MMO (though Oil Analysis and MSDS filings)

Jax, I'm using MMo at 8oz per tank. I seem to be having positive results. I just read your previous post which says 4oz per 10 gal is ideal. In your opinion, is 8oz too much?
By the way Thanks for your help on this topic.

 

4oz/10 gallons (1oz to 2.5 gallons) is the standard dose.

You can see additional lubricity and cleaning up to 1oz/1 gallon, but going over that will not provide any more benefit (but won't hurt anything either - per Marvel).

I use 8oz per fillup of about 12-13 gallons and it seems to be working great in my 8 - I like that one quart gets me exactly 4 refills, nice and neat.

You could use a more (up to 13 oz for a 13-gallon refill) if you want even more lubricity/cleaning or use a little less towards the standard dose.

 

I just started premixing this week. I read someone started premixing and some of their problems went away.

After 3 visits to my local dealer and 1 to Wayne Mazda (a very respectable dealer) I was told by both that I needed a new engine. They both said my car was misfiring when cold but when the engine reached 65 degrees the misfires stop and the car runs fine. Both couldn't figure out the main reason, but Wayne Mazda said whatever was happening it is inside the engine and would need replacing. Invoice says possible rear rotor bad seal. I'm hoping premixing will help.

i was quoted $4800 parts and a $1000 core fee plus about $1000 labor. Total $4800

 

I'd personally only recommend 3-4 oz of premix per full tank.

 

1 Only castrol GTX 5W20
2 none whatsoever
3 only fuel injector cleaner every so often. Probably once a month.

 

Not to be callous about your situation, and fully cognizant of your need to vent -

why are you in the Pre-mix thread?

Your situation has less than nothing to do with the topic......

S

 

Because I just started premixing in the hope of maybe it will help my engine.

 

And being that premixing itself is done for lubrication and to reduce carbon build up in the engine I wanted to 1st state my situation. I meant to state in my post that I started premixing in the hopes of saving my engine.

 

Thx, that's same as me. (And I use Wayne Mazda, too.)

 

You and Jax seem like great sources on this subject. I know there is endless debate about how much and what to premix, but why do you suggest only 4oz? And would that be across the board for any premix or only for certain types (2-stroke for instance)? Thanks.

It seems to me it's like taking any medication- you should use the least amount necessary to accomplish the wanted result. If using 4oz of MMO provides the same benefit of 8oz, I'd rather use 4.

 

We're trying to mitigate carbon deposits. If you've ever seen a 2-stroke engine running too oil-rich you've got a good idea of what too much oil means in terms of carbon production.

As to the ideal concentration, I'd say Marvel has some clue as they've been selling the stuff for what, 80 years?

 

Funny thing TruServ is located in my city... but they are not sure if I can buy it here :|

UPDATE:

You cannot find this thing in most Major Cities Across Canada...you have to get a Tru Value store (which are only located in smaller towns) to order it in for you and make the drive out there. The person I talked with at TruServ said I am not able to go to their warehouse (which is located inside my city) and purchase it directly =( If anyone has alternatives on how we can get good cleaning properties and lubrication it would be awesome, I have lots of Idemitsu Premix at home would I be able to combine that with something like Redline SI-1?

 

Check your thread

 

I don't think RG and I are really of a different opinion. If you were using a 2-cycle premix only, which is primarily a lubricant, I think 4 oz is enough. But if it were me, I would mix this with a lubricious cleaner (and how much depends on which one) for a higher total.

What Swoope is doing is perfect for a 2-cycle/lubricious cleaner "brew" (now you have to appreciate that one!) - 4 oz 2-cycle (IRP) with 2 oz FP Plus (2 oz per tank is max for FP Plus as it is very concentrated), for a total of 6 oz.

That said, MMO is a slightly different beast as it's concentration is different. MMO's standard dose is 4 oz/10 gallons, which would be about 5 oz in a 13 gallon refill anyways - I am just suggesting bumping up to 8 for a little more lube and cleaning. Marvel, through a question on their Forum, stated that the maximum useful dosage is 1 oz/1 gallon - so you could go as high as 13 oz for a refill - so my recommendation is well below the maximum useful dosage.

 

Ok, thanks. And as far as this mineral spirits thing goes- while it may be used for cleaning a disassembled engine, it won't hurt a running engine? I assume not since it's been in use for so long, but it does seem odd to run mineral spirits through my engine...

 

If you are still going to retain the stock omp which I'm sure everyone here is, you should keep the premix low to around 3-4 oz per full tank. You only need to get a very small amount extra into the engine to get to the center of the apex seals. If you had no omp whatsoever and were completely relying on premix for all of your needs, then you'd want to go higher.

 

Solvents, which Mineral Spirits is one of, are in almost all over the counter fuel cleaners - and for that matter gas companies use various Solvents as part of their standard additive pack. The trouble is that most gas companies only use the bare minimum required by federal law, which is not enough to keep most engines clean - the amount required by federal law was cut in half a few years back to save the oil companies money.

The brand names tend to do better with cleaning additives, with Shell likely the best (and most expensive in my area). Shell V-Power is advertised as having 5 times the federally required cleaning power (e.g., additives), the mid-grade and regular have twice as much as is required.

So, as long as you don't use so much solvents in your fuel that you cut into your oil film (only applies to rotary's for the OMP and Premix oil), they are a good thing for keeping things cleaned up. In the case of MMO, the Mineral Spirits are in the right proportion to not effect the lubrication it is also providing.

 

jax.

wondering.

would you take a shot at comparing cost between

mmo @ 8oz

vs

syn 2 stroke @4oz + fp1@2oz (btw this is working very good)


beers

 

Here is a comparison:

MMO
$3.33/quart (at Wally World), plus tax = $3.48
Each quart gets 4 tanks (at 8 oz each) - $3.48/4= 87 cents/tank

IRP (4oz)/FP Plus (2 oz) combo
IRP is about $6.25/quart total ($75 for 12 quarts shipped plus tax)
Each quart gets 8 tanks - $6.25/8= 78.125 cents tank
FP Plus is about $57.75/gallon (delivered and taxes)
Each gallon gets 64 tanks - $57.75/64= 90.23 cents/tank
Total for combo is 78.12 cents (IRP) + 90.23 cents (FP Plus) = $1.68/tank

So you can see, MMO's total cost is almost half per tank of the IRP/FP Plus combo.

Note that for the IRP/FP Plus combo, the FP plus is the major cost driver (great stuff, but expensive) and shipping charges impact this analysis as both are mail order only. Also note that if you use a more expensive 2-cycle (AMSOIL, RP , Redline) the difference gets even higher.

Another interesting combo would be MMO/IRP - but in this one I would do 2oz IRP and 6 oz MMO per tank. Cost would be just slightly higher than straight MMO. This may be another alternative to save over the cost of the FP Plus use and for those that have some doubts about MMO's lubrication ability (which I do not have).

FWIW

 

Shipping is the main problem. I ordered 2 quarts of Idemitsu premix from Mazdatrix at $9.10 total and paid $26 shipping UPS 2 day air. Almost 3 times as much to ship? That's crazy!

 

I bought 12 quarts, it was $50 for the oil and 20 for shipping.

If it's a flat rate, you're better off getting several cases worth of it so the shipping isn't as bad.
