Thoughts on synthetic oil

[chuckkent]

II Kings, Thx. No doubt in my mind that Synthetic oil is superior to dino in a lot of ways. When I worked a Lockheed we used synthetic oil to heat treat aluminum aircraft parts and it was kept at 700F and didn't smoke. I noticed that Wally world has M1 for $18 in the large jug which is a bargain and if I start changing my oil again that will be one of the oils I consider. I garage my car so it never gets below 45 degrees. On all the new 5w oils they have made them so slippery you shouldn't use them on wet clutches on motorcycles and if you try to pick up a screw driver by the blade dipped in the oil it is obvious how much more slippery all these oils are. I was told by Chrysler people that their oil is a blend and has all the properties needed for a long life with MDS. So being lazy I will stick with them until I find out different. Northern says he gets his full synthetic oil and filter for $21. Knowing the prices in Canada this surprises me. If I could get the same deal well need I say....My opinion stays the same as far as whats minimally needed and what we spend extra for....

Northern since I have had three years of college calculus I would gladly go head to head with you on quantum physics, but really is that applicable here. I just don't want to you get screwed by wasting your money on high priced oil......I have narrowed my conversation to things I really know about. And we are mainly talking about the price of lubricating oil not whether synthetic is superior to dino oil. I mean you try to tell us that the rolling resistance of a tire inflated to 30-32 pounds will roll easier than one inflated to 35. I can't let crap like that go unchallenged........

Chuck, Bucyrus is pretty cold in the dead of winter. Take your favorite 5w20 and a qt of Mobil One 5w20, leave them out overnight on a -10F night. Pour a little out of each, guess which one will flow like molasses and which one flows as if it is +90F outside. That is in your engine.

Having said that, my dad's Town Car went 155K on cheap Jiffy Lube filters and plain oil every 5K or so and it ran as new and did not use a drop of oil. Same for my brother's F150: 247K on cheap filters and oil.

I use synthetic only because it is superior and worth the $4.50/qt not $10. I just got 5 qts of mobil 1 and a mobil 1 filter for $27 at Advance, Wallys usually has 5 qt jugs of M1 for $23 (not the turbodiesel 5w40 and rarely the 5w20). I go 15K or 1 year on the S430, 5K on the Ody and MDX b/c of the dainty filter, and now 7.5K on the 300C (previously 6K). You can go 3K on regular oil if you like but don't kid yourself about saving money. I don't think regular oil will do any harm, it might make a difference past 500K miles or so. Most of those old MB Diesels with 600-800K did it on regular oil.

You know it is even worse, that 5w-40 alot of us use only comes in 4 qtr size.....so we get even less

Are you really that completely thick to miss the point entirely? Are you seriously that clueless? Your complete ambivalence in this and the other threads is irritating, confusing and is the sign of someone that is so buried in the BS he spews that he cannot make out a difference anymore.

you don't even know what you are talking about anymore.

No one is getting screwed by anything other than your BS info filled with misinformation, old wives tales, urban myths and 1960s-70s oil and automotive knowledge.

Yet you just keep on and on and on with the same BS line and every repsonse is covered with some other BS reason that you know better like your computer store sitrict manager or fleet manager training along with the award winning delco tech son.

It is getting hilarious. Soon you will spill something about a relative working as an engineer at an oil plant and that you know all because of that.

What crap? The fact you were trying to preach that we all should be inlfating their tires to 40psi to save fuel when it makes zero difference and the fluel saving will be offset by suspension damage, wear and replacement?

The fact is, you got that thrown back in your face by me and others and you ran away from that thread like a wimpering dog that got the correction it deserved.

Anyone preaching that they should turn their luxery car into a barn wagon to save $20 a year is someone that should have bought a prius, but yet are still delusional enough to buy a 350HP HEMI.

Just like the half gallon ice cream is now 1.75 qts. I can't find 5w40 M1 in the jugs, I bought all the qts that advance had on sale. I notice the synthetic 5w40 Shell Rotella T Diesel (blue jug, not white) at Wallys in the 4qt jug for for $19 which is an option for the S430 at next year's oil change.

Im getting confused as to where you worked, you have said a computer shop manager, Lockheed and currently at chrysler as a fleet manager, but you also said you are retired? just wondering what the real deal is?

BTW synthetic oil doesnt cost $10 again we buy it for $4-$6 a quart. and it is readily available for that price.


Also we are having this discussion because you say its cheaper to run dino but as many have pointed out over and over again it is actually cheaper to run synthetic oil (it costs about the same per quart and lasts much longer based on evidence from analysis not oil companies)
So your first myth is busted.

Second, you say it makes no difference, fine run what you want to run but we all know and its common knowledge that your engine does better on synthetic.

Amen,

Thank god someone sees all his credientials being thrown around are unrelated and a sign of a complete BS'er.

Yep, I have worked in all the places, plus I was a instructor at a prominent electronic institution, customer engineer, etc. I'm old as you say...and have had the privilege of wearing many hats. I prefer synthetic oil OK, but you can go to Walmart and use any oil they have if it meets the API specs recommended by the mfr. of the vehicle and you will experience no detectable difference: Not gas mileage, meaningful length of service life, or increase of failures in the average car. Do I prefer certain brands? Yep and cost is an important part of it. If your income is limited you try to get the most bang for the buck. This is why I am completely debt free and can buy most any thing I need. I prefer to spend my money on things I enjoy most. If you like spending money on oil products my hats off to you. Northern, I missed the point on purpose cause you are usually so busy railing on me you don't comprehend it if I tell you straight. The real point is that my son in law and I have long lengthy conversations about various functions of the automobile and I try to learn and trade past experiences so we both get smarter. When it comes to tire pressure, octane, oil my references are backed by science, mfr recommendations from Chrysler, Goodyear, and the oil rating industry. I don't care if my crankshaft after 300,000 miles has one ten thousandth more wear, or a dynamometer shows I have 2.00 more horsepower at the rear wheel. I consider myself a motor head but not too extreme.. I have tried to be civil but you follow me around these threads like a plague, put words in my mouth. I know there are a lot of folks out there shaking their heads at us but, some are sick enough to enjoy the pot shots we have taken at each other.....

OK, I'm going to have to defend Chuckkent as it seems some of you are twisting what he's saying, plus what he is saying as I understand it is basically correct.
You don't need to run synthetic oil in the 5.7L...otherwise that would be the factory fill and the manual would point it out. Also, he is correct, today's dino oils are way ahead of those years ago and I'm sure good enough for the 5.7L Hemi to live a good long life on following the Chrysler's oil change intervals. I run synthetic, specifically Mobil 1, because I've had great results with it over the years and I like the piece of mind that it might be providing some performance benefit over dino oil. I say to each their own. BTW, he is right that you can spend $10 per qt. on synthetic oil. Just look at Redline oil, which personally I feel is the best synthetic oil available. Its $9.49 a qt. Now is it twice as good as Mobil 1 which you can get for around $5 a qt.? I don't think so, nor do I buy into the Amsoil 25,000 mile between oil changes advertising.
One thing where I think Chuckkent is wrong and basically wasting money is changing oil at 3,000 mile intervals. With today's oil, even dino oils, there is no reason to change that soon in my opinion.

BTW, to think that you will be damaging the suspension by inflating tires above the factory rating yet still within the tire manufacture's rating is quite laughable.

Oh wow, since when has Chrysler recommended 87 octane, Goodyear specified you should crank the tire pressure up to 40psi and since when has Chrysler said that synthetic oil is snake oil that is not recommeded seeing it is not the factory fill.

All of those things are you pure conjecture based on zero financial or economical gain, zero automotive knowedge and are nothing but your pure opinion.

We are not putting dino oil down, but you are putting synthetic oil down as being really expensive, which it isn't, and snake oil, which wear results have shown that it works. Plus, it is the cheaper oil change.

But again, you will go on and on how you are saving money, when for all three issues, i bet you I will be financially ahead in the long run, plus I won't be running around like a cheap old man on 40psi rock tires and an engine pulling timing while pulling my car into a Chrsler dealership to be raped without lube for a $32.50 standard oil change.

To bad your dimensia has collective destroyed your common sense when it comes down to financial numbers and saving money.
