Well stated. There is a very popular ester oil based engine cleaner here on this forum. I am currently using it on 3 of my 4 vehicles. However I have been trying to figure out which full synthetic oil contains the most ester oil for this very reason. No sludge formation, no additives or extra...

In the next 2 weeks I will be changing out the headgasket. I have every reason to believe that most if not all the leaking oil is coming from the head gasket area. I finally picked up a small inspection mirror to checked under the injector area and yes oil is seeping and dripping from the...

Funny . . . I like the spaceship analogy. Actually HM oils are more robust and generally have a better additive pack than regular oils thus less wear. Leaking oil is not a big deal but a nuisance with the exception being is when a leak contaminates a zero tolerance timing belt and contributes an...

I did a search and no brand names where listed however there was mention of doing a leakdown test. So will a regular compression gauge also do this? Any recommendations. I'd rather pay more for a product not made in China. I will doing a headgasket change on my 1/4 million mile Civic and I...

Another thought . . . not trying to be a pusher for Mobil 1 High Mileage oil but you might try it in the 10w-30 weight during the winter and if consumption doesn't drop after 3 quarts or so - go with 10w-40 version & in the summer. Mobil is making a tall claim on cleaning up crud in the motor...

Why wouldn't any of the 15w-40 HDEO be just as good? Ever wonder why we never see a high mileage HDEO?

Maybe in my original post I should of compared Super Tech Synthetic 5w-30 instead. I really didn't want the dino vs. synthetic to be a major issue, however I have also read posts here where dino user have relatively low wear numbers compared to synthetics. So now it seems that the additive...

Um . . . I'm not even sure I'd want to even run Amsoil 0w-30 under these conditions for 15,000 miles. If it was me, considering the conditions, I would pull a sample in the 5,000 to 7,500 mile range. 15,000 is a bit long under these conditions. I've run synthetic oil as long as 15,000+ and...

The maxlife advantage is that is offered in a 5w-30 weight in both a blend and full synthetic where as M1 HM is only offered in 10w-30 & 10-40. To be fair the caparison needs to be with the synthetics only and not the MaxLife blend. Mobil HM has a fairly tall claim on cleaning ability. Time...

Precisely the info I was looking for and at a price I can justify. I never pay over $4.50 a quart for any synthetic oil. Thanks

Honestly I've thought of prefilling but never have done this. However in the interest of not loosing sleep over this I will compromise and at least dampen the filter media. I figure my engine oil pressure will go out 0.34 seconds quicker than with a media completely dry. Honestly I figure the...

Price in my area is just over $6 a quart. I'd like to buy it for right around $4 a quart - is this possible? Any upcoming sales. Local stores near me last I checked had a decent stock - more than what I could use in 5 years. Yes the gold stuff.

I constantly hear "you can use most anything for that short of a OCI . . ." I'm skeptical of this premise. Experts and fellow skeptics please chime in. For example Joe Six-Pack uses Super Tech dino 5w-30 known to be a tad thin on additive pack. And he changes his oil every 2,000 miles...

What is your application and how cols does it get in your area this winter? I'd give the 10w-30 a slight nod due to the possibility of keeping your engine cleaner or removing existing sludge. I will be using HM M1 10w-30 next spring once temps are solidly above 25 degrees or so to see how it...

AFmedic, Don't be in big hurry to drop your current oil - get your $'s worth out of it. If your concerned about warranty just stick with what you have. This exact oil will be my winter oil. Temps in my area drift down to an occasional below zero and do spend a fair amount of time in single...

Seriously what does this really indicate? All joking and puns aside.

Is this in any way related to ink blot reading? You know the psyche testing stuff?

However does the "FULL" synthetic contain any PAO? Maxlife "Fulle Syn: PDF Available?

I remember seeing some UOA that seemed to indicate some difference from the plain version however there seem to be enough variation form the various lots . . . so that seems to be in question. The 5 quart Jug @ China Mart of SUV M1 was only $19.xx so I bought it. It was cheaper than the gallon...
