Engine Oil
 

My roommate pointed this website out to me, I have yet to read it but from skimming it very quickly and what he said about it, it looks to be well worth reading. Looky Here

Very interesting article. Moved to Good Stuff.

Interesting...Of topic but 1ViciousGSX thats the sweetest picture ive ever seen. Whered you take that at?
:3gears:

On the topic of synthetic oils, what do you guys think of Amsoil.

I know it is really expensive, and I ahve heard people who love it to death, but recently a friend of mine, who I trust when it comes to his knowledge of cars, claimed that amsoil was shit.

What do you guys think, and does anyone have any first hand experience??

Amsoil is like your mom and the big oil companies are like Keebler. With Keebler you always get the exact same cookie no matter which bag or batch they came from. With your mom, the cookies are generally good but they never quite taste the same. Unfortunately, your mom will without a doubt burn a batch here and there and when that happens they just suck ass. Basically what I am trying to say is that Amsoil doesn't have the quality control larger companies too. Amsoil also uses all short-chain oil molecules which are great for performance but no no protect the engine as well as a short and long-chain mixture.

P.S. I'm guessing that friend of yours was Reid?

wow that was a really good simileeee

You would be guessing right. I hate it when that kind of thing happens, b/c as you know, reid knows a fuckton of stuff about cars, but then, a whole lot of people like amsoil, so its like, who do I trust.

Anybody need 2 quarts of full synthetic 15w-40 amsoil??

Have you noticed that only hicks like Amsoil?

Amsoil is the way to go. I was using competitors oil and temp. was not good. Used Amsoil synthetic and brought temp down 5-7 degrees. Been using Amsoil synthetic after 700 miles on new engine and never changed. I would not move to synthetic if allot of miles on your engine. Also synthetic is thinner, so can get to other regions of engine that normal oil cannot. Net effect is longer lasting engine. Then I got aftermarket radiator and oil cooler and brought down temps significantly more.

Do you really want to take advice from someone who believes hicks use Amsoil. I must be a yuppy hick from the city! :bounce:

I dont take advice about oil from someone that doesnt believe in synthetic period... :stick:

Synthetic oil is not actually thinner, it is just more slippery because of the lack of impurities in it. If it was thinner it wouldn't be the same weight. I have used many different kinds of synthetic. Amsoil seems alright, but like someone stated, the batches vary. I seemed to have settled on Valvoline synthetic for now. Castrol used to rock a few years ago, but they are not a true synthetic any more (they use a cracked hydrocarbon base). Mobil 1 is good, but does not have a lot of additives and my cars like to lifter tick with it in there.

OK so now for those of us with high miles, what is the best thing for us to do. I've heard it's bad to switch to synthetic on a higher milage engine because like you said, it can get into places other oils can't, which in turn can clean out any little tiny build ups that are actually aiding in sealing up certain parts of the engine. So all a sudden u have leaks from all over. That's what I've heard. I don't think I've ever owned a car that had less than 90k miles on it, so I've never used Synthetic because I have heard this. My talon has like 102k on it, so I just run Valvoline 10w30. I'm afraid to switch to sythetic for the above reasons. Anyone here an oil god that can maybe gimme a little advice?

Also I wish there was a study like this on regular oils since that's what I always seem to use. Anyone know of somewhere with a study on regular oils?

I just would not change to synthetic because miles on engine. I used the word thinner before. Yes oils are same weight synthetic compared to regular oil. Basically I drove 700 miles on new engine, then changed to synthetic and a little oil got past rings, I got a little blow by. Can tell when look at spark plug. By next oil change engine is used to synthetic. Mabey change to valvoline max life.

Thank for advice. You talk good. I am job.

hahaha, ohhh gotta love the Engrish speakers.

anywho, i am a Mobil 1 devotee

when i received my old maxima at 170k, i immediately switched to Mobil 1 and it never leaked a drop up to its 212k demise (water pump)

i just trust it, and it seems like all the new kick ass cars come with Mobil 1 from the factory. plus you can buy it in 5 quart jugs! wooot

who cares? most DSM's break before the the oil change interval anyways, or leak it out, or whatever....

but i guess i do use M1 on my new car, not sure why, just do.

It is not recommended to change to synthetic on a high mileage engine when it has been running standard oil forever. The reason is because synthetics contain detergents that clean away oil deposits in the engine. These very oil deposits are what are sealing up worn gaskets and seals preventing oil leaks. If you switch to synthetic on an older engine you will most likely start experiencing very small oil leaks.

Jason, if you got blowby on an engine after 700 miles it doesn't magically disappear. You would also notice smoke coming from your exhaust before you'd see anything on your sparkplugs.

Mabey, must not have had blow by, noticed a little oil last year on spark plug after first use of amsoil, next oil change, nothing. Certainly never saw smoke. I do agree that should not change to synthetic after you have been running regular for long time. :3gears:

Agreed. I've used Mobil 1 from the day I bought my car. Never had problems so why change.

And I love that I can buy the 5 gallon jug :D

So what do u guys recommend on my car? I've been running Valvoline 10W30 forever and I have about 103k miles. Stick with it? Still change it every 3k since it's not synthetic?

Rotella-T is what you need. It is like $6 for a gallon and it is heavy-duty oil designed for turbo use.

Rotella's cheap. You get what you pay for. ;-)

Try and find a better performing conventional oil for turbo applications. I know people who have switched from Mobil1 and never gone back.

And I bet there are more who swear by it. There is a reason one sells more than the other.

Which is used by more long-haul tuckers? I'm not trying to change everyone's opinion on here...I was just making a recomendation to ME612 since he asked for it. Some people swear by synthetic...some don't. Everyone should use whichever oil they personally feel is best.

ME612- I think you will be fine with valvoline oil.. either regular or synthetic. I have never used Valvoline but they are a good brand. And as JET said, the valvoline doesnt lifter tick as much.

Personally I have used Castrol Syntec in my car ever since the rebuild. Its great for lifter tick ( I get none). I switched to Mobile for one oil change and ever since that one of my turbo's copper washers has been leaking a little and I noticed the oil pan leaked a little too. I know Mobile one is great oil, but in my car it lifter ticked ALOT when cold and liked to penetrate a little too much for me, so I switched back.

Higher mileage motors- I wouldnt switch to synthetic.. not worth it and it will penetrate through gaskets and other things that were mentioned before.

which for me is the cheapest 5 quart jug i can find at walk mart. lol

Supertech oil is actually cheaper if purchased by the quart instead of the gallon.

i bet it'd be cheapest if you bought it by the drum

Just for reference, I bought my car at 92k and it now has 192K. I've been using Valvoline 5w-30 in the winter and 10w-30 in the summer and haven't had any problems yet. (I'm sure now that I've said something though I will :)) It's been changed every 2500-3000 miles and the balance shafts haven't froze yet so I'd just stick with with the cheap stuff. ;)

Here is another interesting article: http://www.motorkote.com/oil_analysis.shtml

I have used Royal Purple on all my cars/trucks since 1996. Before that I used Valvoline exclusively. I believe it is the best you can buy! I watched (in person) a bearing load test and Royal Purple won hands down above: Mobil 1, Redline, Valvoline, Amsoil, Castrol, etc.

Well personally here I have always used the cheapest shittiest oil that I can find, you know the stuff you find at the convenience stores like caseys brand and fire star from kwik star and i just never change it and never had a problem with anything yet.........................Im just bullshittin!!!! I personally like Castrol GTX, I have used this in every one of my cars. It has always treated me well and it is relatively cheap!!!

Why didnt I read this thread before I did my last oil change. I went from normal oil to Valvoline's Synthetic oil and my car is at 99K right now. Is that considered HIGH mileage? I'm about due for another oil change in like 1 week and a half, so I'll probably switch back to the Maxlife 5w30. I wonder if I change back to normal oil, my valve cover would stop leaking a little.... :banana:

Kendall is also reputed to be an excellent non-synthetic (kendall gt-1) .. it's sold at bumper to bumper stores

Valvoline now sells Maxlife Full Synthetic oil. Thats what I'll probably be getting on my next oil change....(I get 50% off everything, isnt that cool). I dont know how much they charge for that kind of oil, but I'm guessing it'll be the same as their regular Full Synthetic.

well changing oils alot isnt too good for a car, synthetic may last u more milies but if u keep changing it to a diff kind over n over, its not good. ive read taht its best to chose a oil type and stick with it, doing that is good enough, high milage stuff is just for marketing purposes.

Regular Maxlife actually has a very good additive package in it, I don't know about the synthetic stuff though. Our new friend with the wierd name is right though, it is best to choose one kind of oil and just stay with it (thats why its always a good idea to ask previous owners what type of oil they have used).
