Mobil 1 oil

Re: Buttinski! (Mobil 1 oil)

Mike, I work at one of those gas turbine manufactures, that produce some of the engines you listed. I have asked several of the guys that design the bearings and lube systems for these engines what they use in their own cars and trucks. Everyone that I asked used conventional oil for their personal use. They felt that synthetics were not cost effective for their own use even though they specify them on the gas turbine engines we design and sell. These guys have had the discussions of synthetic vs conventional oil many times and they said there was only one person in their group that uses synthetic in his cars. He runs extended drain intervals, but does not do oil analysis. That is how he justifies the cost.

Thanks Mike,

Thats the kind of user-observation I like to hear.

Re: Buttinski! (Mobil 1 oil)

IMHO analysis is a no-brainer for ANY expensive engine-driven machine. At $11 from the local CAT dealer it's so little $$ in comparison to even a minor repair that I can think of no good reason not to do it--whatever oil I'm running.

Let's face it--if you're even taking the time to read this thread you've gotta be a little obsessed /w3tcompact/icons/wink.gif Once you have a string of analysis reports on your truck/tractor/whatever, you get a nice warm fuzzy feeling about her and it can't hurt the resale value, either--how would YOU value a used machine that had a complete oil analysis history versus another you were considering? Another $1000 or more not a big issue to know you got one that was really cared for?

Andy you sure hit that one out of the park.

Wife has brought this up a number of times...tractor's washed more, fed better, strained less, on an on. If you want a well cared for tractor when I die there'll be 4 of them here. If you want some organs for transplant...that's another story!

I'm sure I'd be better off getting rid of the tractors, picking up a shovel, pick, rake, sickle, wheelbarrow and eating straw everyday. What's that old joke? I can't remember whose quote this is..."Do (whatever) you'll live longer" "No...it will only SEEM like it's longer!"

Re: Mobil 1 oil (buttinski!))

Larry,

Ditto!

A few KB of type hurts no one. I have read it all too, we just have to go with what we believe is best as there'll probably never be a real world comparision that satistifies us all. There's the group that believes oil as so improved that 3000 mi changes in normal service cars and trucks is ridiculous, or that the 6000+ that is now recommended in many cars and trucks is risky. I'm somewhere in the middle, most of my cars and trucks go 4000-4500 oil and filter, just plain Castrol or Kendall. RV gets 3000 mile per change, it and the tractors use 15/40 Rotella.

When I change I do it warm and let them drip forever, and try to fill the oil filter w/20/50 (so it doesn't run out) to try to keep the pressure delay down to a minimum. That's my obsessive compulsive oil behavior!

If I was somewhere colder I might have to change things!

A friend worked on the Alaskan pipeline, has told me stories of how oil up there turned to almost grease, how diesel turned to something akin to hand cleaner (jello). Door handles would break like glass. Engines would have to be heated when off or forget them. That must have been something up there!

And thanks to all that post no matter WHAT your opinions are, what you may think of as irrelevant is NOT. Supposedly from the board stats theres a few hundred of you not ever posting. That is a loss, jump in! /w3tcompact/icons/smile.gif

Re: Mobil 1 oil (buttinski!))

GlueGuy, your comment about the oil being clear being a good sign is against what I've been taught, that in normal use oil should look dirty after 3000 miles or so (at least) if it isn't the oil isn't doing it 's job, keeping the dirt in suspension. ??? Wrong???

Of course what I'd like to see is that the oil is clear at the oil change with the filter holding ALL the dirt!

Doesn't seem to be the case, have tried different brands of filters just for fun, doesn't seem to make a difference, at least naked eye wise.

Trescrows, actually you have to use BRACKETS [ ] around the word, not the Parenthesis, here they are: Put the brackets around the words shown to get the little drawing.

Re: Buttinski! (Mobil 1 oil)

Thanks Larry, that is interseting. From a statisitical point your sampling "rate" would not be considered sufficient to be relevant but it is interesting to this topic. Have you done other oil samples since you have been using the Amsoil--do you ever finds spikes or differences that are still considered normal. What are you using as a base line --ie how much Al or Fe in the oil etc is normal for that engine or type of engine. (smile)
I forget who asked up post somewhere if I had already used the Mobil 1 in my BX and the answer is no--I am at 97.9 hours so it is time to change oil--thus my interest. I would not use a synthetic probably before 100 hours as the rings might not seat properly.
Did my Toyota go 300,000 miles trouble free on the original engine because it always had Mobil 1 oil? or did it go 300,000 miles cause it is a Toyota?, would it have gone 300,000 miles with Quaker State/Pennsoil/ synthetic/conventional whatever---who knows because my one sample--my Toyota is not statistcally relevent either. My gut tells me it is a combination of Toyota quality and Mobil 1 oil. My parents bought a Ford van from me with 25,000 miles on it back in 89 and I had used Mobil 1 oil from after break in. It used no oil at all and ran great with good fuel economy (for a van). My dad continued to use Mobil 1 for another 25,000 or so miles and then began using Texaco Haveline because a local Texaco had a little mechanic fellow that was real good on small jobs and that is what he had. Oil consumption went up immediantly and fuel economy dropped also and the engine just did not seem as happy (subjective). My Toyota gets 5,000 mile changes, so did the van and so does my Tundra and so does my wifes car. I have always done 5,000 mile changes since using Mobil 1. I would not be afraid of going 7,500 miles in a car seeing ordinary use. Unfortuanately it seems everywhere I live, AZ and now KS are rather dusty so 5,000 is it for me.
I was hoping to hear that some of you guys had used Mobil 1 in your Kubotas but nonetheless some good info here --thanks. J

Re: Mobil 1 oil (buttinski!))

TresCrows, CORRECTION!! /w3tcompact/icons/shocked.gif

I know I am getting old,... but I didn't realize how the process has accelerated.

I tried, BUT: All my carefully worded "instructions" for adding smiley-faces, if followed as-written WILL NOT WORK!

I repeatedly said "parenthesis", when I should have said BRACKETS, like this [ ] . ( I used brackets in the examples, but should have described them correctly as well). /w3tcompact/icons/frown.gif

Thanks for (inadvertantly?) pointing this out to me. I realized what I had done when I saw the (smile) in your most-recent post. (checking by "previewing" will help you catch these things.)

Sorry for the "bum-steer" /w3tcompact/icons/blush.gif

Re: Mobil 1 oil (buttinski!))

How come none of you guys pointed out that I had posted bad info? /w3tcompact/icons/crazy.gif

I'm counting on the "group mind" to save me(and others) from myself when I do that.

Hello?,... Hello? Wake up out there! /w3tcompact/icons/wink.gif
