Oil Type?, what type is best Options

[Bitter]

look on the front of mobil and you'll see a little * then look on the back and it says something about a non synthetic base oil.


the BEST way to clean the innards of your engine is with some ATF every other oil change. add about 1/2 qt 100 miles before the oil change.

Hey Bitter, would you be convinced that switching to synthetic can cause your engine to leak oil if I found an article written by an Amsoil representative that said just that?

Why synthetic oil can cause leaks

So much for your myth theory....

I read the whole article. Surely you are not going to maintain your myth theory after reading that? Just so you know, its ok to be wrong. It happens to me all the time. When I am wrong, I just admit it and go on. No big deal!

Fortunately, oil manufacturers learned their lesson and reformulated their oil to contain the proper additive package which helps condition seals and gaskets to maintain their flexibility while also maintaining proper seal swell. In fact, the reformulation in most cases provides for better seal conditioning than most petroleum oils these days. Nevertheless, there is still a possibility of leakage if making the switch to synthetic - but only under certain conditions. Please allow me to elaborate a little bit.

Any of you who are considering a switch to synthetic oils probably know by now that petroleum oils do not necessarily keep your engine squeaky clean. Well, if you own an older vehicle (over 8-10 years old) it's possible that you have leaks in your engine already. Now, before you string me up by my toe nails telling me there's never been a drop of oil that leaked from your engine, let me explain myself.

On older vehicles which have been lubricated with petroleum oils, seals and gaskets can begin to dry and crack. The reason you don't actually see leaks is because petroleum oils tend to burn off and leave sludge, grime and varnish on the inside of your engine. That's simply the nature of a petroleum oil's make-up. Now, conventional petroleum oils are not very discriminatory about where they leave those deposits. Therefore, some of the deposits end up around your seals and gaskets which actually plugs up the gaps which would have resulted in oil leaks.

Not even close. The fact is, it's a result of using petroleum oil instead of a high quality synthetic that resulted in dry and cracking seals & gaskets in the first place. As I mentioned earlier, synthetic oils now contain special additives which maintain proper seal swell and keep them flexible so that seals and gaskets don't dry and crack in the first place. So, for those people who use synthetic oils from the start (after a 3,000 to 5,000 mile break-in period), the problem never becomes an issue.


so i guess you didn't read that part of the propaganda realy close? it says you engine is leaking but you just dont see it.

and i still dispute the validity of this article since it was written FOR Amsoil by someone who sells Amsoil.

If you are going to quote the article, it is best to quote the relevant portion. Fortunately, its the part that came right after the part you copied. Since you might not have seen it, I will post it here for you:

Of course, the next obvious question is, "If synthetics have those special additives, why might they cause leaks in an older engine? Why don't they correct the problem?"

Believe it or not, I've got an answer for that too. The "problem" is that there are also other additives that give a synthetic oil its detergency properties. In other words, there's other stuff in high quality synthetic oil which tends to clean out the sludge and deposits left behind by petroleum oils. Once these deposits are gone, the gaps around seals and gaskets become exposed and the oil might begin to leak in these areas.

As for your argument that this was written by an Amsoil dealer so that means the information is suspect, lets think about that. Amsoil makes synthetic oil. Therefore, if they are going to "spin" the article, they are surely going to do it in favor of synthetics. Here they admit that switching might cause oil leaks. Why would that admission be biased?

I switched to mobil1 at about 75000 and have noticed consumtion.
Don't know where its going can't find leaks but its going somewhere.

Maybe they are trying the old reverse psychology thing. I never really thought it was debatable if synthetics could help the leaks leak. They don't cause them themselves necessarily, but they will open up holes that were plugged by petroleum oils. All that needs to be proven is that synthetics have a detergent or cleaning additive in them that can break up slug left by other oils. If that can be proved, there is no contest here.

give it some time or try sucking some ATF through a manifold vac line into the engine and then letting it sit over night. ATF has awesome additives that are GREAT for rubber seals in engines and transmissions as well as very strong detergents that will help to clean the intake manifold and combustion chambers somewhat.

What is ATF? I wish people would type things like that out sometimes. Those abriviations aren't universally understood.

Are you serious? If you are, how was I supposed to guess that? I have never heard of this, and I am a bit sceptical to say the least.

its one of those things thats passed from mechanic to mechanic. trust me, it works. it also works GREAT to clean out the sludge/varnish in your engine. its got some great detergents, run about 1/2 qt in with your oil for about 100 miles prior to the oil change.

Yep - works pretty good. It's because of the additives in it. You don't want to run long with it in there though - just a few miles before changing your oil.

Mobil 1 10w-30 is the best. I did a lot of research at one point to figure that out. I didn't save any of it, but if you do a search I'm confident that you will come to the same conclusion. It's the best for the money. Racing oils are better, but cost significantly more.

Synthetic oil is the best thing you can do for your car period. I'm not even going to argue about it. Mobil 1
is one of the best oils you can put in it. If you love your car, throw some synthetic in it.

Hey Bitter, can I assume that since you have posted three times in this thread since my last post and have not responded to what I wrote that you are now convinced? If not, I would appreciate a response to my last post.

[chacha]

yeah...i put in Full-Synthetic everytime...it doesn't leave that yellowish stain residue on the inside engine bay...it helps to go to high performance oil...Castrol Full-Synthetic...BUT IT AIN'T CHEAP!

[LewFX]

its on sale at pep boys for 1.20 a quart after rebate, i say mobil 1 all the way!

i'll be blunt, i dont care what myths you choose to beleive and hold onto. if you dont think you cant change over and that its the OIL causing the problems then go right ahead and live on your flat earth that the sun revolves around

You are confusing the issue by using the word "cause" since we all know that the synthetic oil is not the initial factor in creating the condition that leads to the leak. I am talking about the part I quoted above about the detergent effects of the synthetic oil opening up areas that will leak. Do you believe there is a risk of developing oil leaks after switching a high milage engine to synthetic oil or not? You can answer with a yes or no. I only ask because I value your opinion.
