oil

tireburner163 · 04-30-2002, 08:52 PM

Well shortly after buying my car, I starting adding Castrol Syntec syntetic oil(at 79K,..I have 96K now). I change my oil every 3K miles. To be quite frank, buying this high dollar oil it killing me.

My question is....Is it ok to switch from my current oil to a conventional oil(Castrol GTX)?

I change my oil at 3K, but I've been told that with syntetic's it's ok to change it at 5K. Is this true?

joe4speed · 04-30-2002, 11:43 PM

you won't hurt anything... I'd rather change regular oil at 3,000 than change any kind of oil at 5,000mi.

fiveohpatrol · 05-01-2002, 12:28 AM

Although I've never had personal experience with it, I have heard of alot of people that try to do that and it ends up using more oil than it did before.

If I were you, I'd try stepping down to some senthetic blend first.

Or better yet, hurry up and trash that motor in favor of a 302

Mach 1 · 05-01-2002, 12:32 AM

Ive switched back and forth several times(although not at long intervals between oil types) with no problems. They are compatible, so I dont see what all the fuss is about. Just do it.

93 VENOMIZED · 05-01-2002, 11:36 AM

Hello All, I'm new to this board. You guys and gals need a good school lesson on the properties of oil, conventional and synthetic. To learn everything you need to know about motor oil, go to www.motoroilbible.com and purchase and download thier E-Book. You can then print it out, it comes out to about 84 pages I believe. Your wasting you hard earned money changing synthetic every 3,000 miles. Petroleum oil begins to break down almost immediately. A high quality synthetic, on the other hand, can last for many thousands of miles without any significant reduction in performance or protection characteristics. Synthetics designed from the right combination of basestocks and additives can last indefinitely with the right filtration system. I have tried several synthetic brands, and the best (in my opinion and experience) is Amsoil. Im currently running 0W-30 weight in my 93 COBRA (with only 8k miles on the clock) and in my 2 Subaru Legacys. Increase in Performance and fuel mileage is immediately noticed. I am not a mechanic nor claim to be one, but I have been driving for 22 years, and have owned 18 cars and trucks, so my experience in using different oils over the years speaks for itself. Well enough of me blabbing on, just go to the sight, and buy the oil bible, I believe its $19.95, you will be glad you did. The information in it is priceless.

fiveohpatrol · 05-01-2002, 12:24 PM

No matter what kind of oil you put in your car, it will still get contaminated by the small amount of fuel that gets by the rings.
Whether its wal mart brand 10w30 or amsoil, it will still get contaminated.

so that said, I'll stick with conventional or a senthetic blend and change it every 3000

I 100% agree... oil is oil and it's still gonna get dirty. I use synthetic, and change it at 3,000 cuz I know it's dirty. Even if it's not broken down yet.

Thats the biggest bunch of bullcrap I have ever heard. You dont just happen to be an amsoil saleman, do ya?

I suggest you do more research before you make such ridiculous claims, and push some worthless "oil bible" for $19.95

RED92LX50 · 05-01-2002, 03:08 PM

That's funny, spend $19.95 to find out about motor oil! HA HA HA. I was having a long day at work, and that really made me smile

I might spend $19.95 if the guy who wrote the article will come over and change the oil for me! (Of course he would supply the magic oil too).

93 VENOMIZED · 05-01-2002, 03:16 PM

obviously your not interested in learning something, which is todays youth problem. Instead of wasting 20 bucks on a six pack and cigarettes, use it wisely and buy the motoroil bible and you will learn a wealth of information about something you have no clue about, except for all the myths youve read about. I have 250k miles on my subaru and Its run only on synthetics since it had 3k miles on it, and it runs as good today as it did then. We can take your engine apart with 50k miles and mine with 250k and mine will look brand new, and yours will look like the bottom of my gas grill. Start up is when most engine wear occurs. You see people all the time start their cars up on cold morning and immediately rev the engine. Your metal to metal baby, especially with your conventional 10/30-10/40 oils. Your engine begs for mercy as soon as your about to turn the key. Now on the other hand a fast flowing 0/30-5/30 great synthetic like Amsoil, and your engine will love you every time you turn the key, wether its 10 below or 100 above. Experience, there is no substitute. That's it for todays class children. Hurry, wal-mart is having a sale!

Mach 1 · 05-01-2002, 03:25 PM

What makes you think for one minute that you know more about oil than anybody else on here? Because you read the oil bible? Lmao.....What exactly are your qualifications? Yeah, thats what I thought.

We have professional mechanics on this board who know a lot more about oil and engines that you ever will, so dont come here preaching your crap to us like were a bunch of stupid, easily influenced kids. Schools out...later

93 VENOMIZED · 05-01-2002, 03:51 PM

A mechanic is not an expert on motor oil, he mostly likely knows as much or less than yourself. Next time you see your neighborhood Joe, ask him to define these oil qualities for you,

1. Viscosity Index

2. Low temperature performance

3. High temperature performance

4. Oxidation Resistance

5. Polyalphaolefins

6. Diesters

7. Polyolesters

8. Anti-Foaming agents

9. Detergents and Dispersants

10. Corrosion Inhibitors

And BTW I am not a Amsoil salesman nor have anything to do with them, I just know (thru experience) that Amsoil works best. Mobil 1 is also very good, but a bit behind the Amsoil when you break them down. An excellent Oil Filter is a must as well. Amsoil, and Mobil 1 Filters are the best. I suppose your gonna tell me I work for Mobil now ha smart A**!

Let's get something straight, all Im saying is that synthetic oil protects your engine better than conventional oil. Its not a guarantee that your car will never break down. Only guarantees in life are death and taxes. So before you all shoot me down, just listen for a second, its not as ridiculous as you all think. No hard feelins guys, was just trying to pass along some useful and knowledgable information.

Mach 1 · 05-01-2002, 04:34 PM

Most people know that synthetic oil is better than conventional oil, and most people who are interested enough to care, know why.

You started this whole thing by some rude remarks implying how stupid we all are and that we dont know anything about oil, and we should educate ourselves and read some oil bible, blah, blah...not the best way to come across and make a point.

A point that wasnt even related to the question that started this topic.

Im not going to get into a long debate with you over oil, its properties, which is better, etc...

I have been working with and studying oil for a long time as a hydraulics specialist and I am well aware of the properties of oil, as are many car enthusiests who are here, and I dont think anybody appreciated your attitude that we were all "misinformed" about oil, which is not true.

RED92LX50 · 05-01-2002, 04:54 PM

The part I find funny is that you would even think for one minute that an educated person would spend $20 for an article on motor oil is ludicrous (if it is that good of an article my local library will have a copy).

Also, shopping at WalMart is not necessarily an indication of ones IQ - but my guess would be that anyone who spends $20 for an article on motor Oil is at the lower end of the spectrum!

Plus, I need to save my $20 for the upcoming release of "Girls Gone Wild Part VIII".

Lmao...excellent points. By the way, Im selling copies of "The Spark Plug bible" for only $26.99. And if you dont read it, you are an idiot and your car will not run well on the spark plugs that you have chosen. So send me your money fast.

1BAD89 · 05-01-2002, 05:13 PM

This thread is hilarious, 93 VENOMIZED: you really came off on the wrong foot, acting like the ALL MIGHTY OIL GOD, and "assuming" no-one else knows anything about oil other than you. Kinda shady in my eyes, then look at what you said.

Before blabbing on and on, you should realize that people other than yourself have great knowledge of oil. Why do you assume that all "todays youth" just buy cigarettes and six packs? That's a screwed up stereotype if I've ever heard one. I'm well educated about motor oil, and I wouldn't waste my money on your "motoroil bible". I think your a bastard for saying that the people on this board have no clue about oil and it's properties. How do you know your engine will look better than mine, yours having 250k, and mine having 50k? YOU DON'T. Then you say that mine will look like the bottom of your gas grill? WTF. Your just rude. I suggest that you buy the "I need manners bible" , you can purchase this at www.Ineedmannersbible.com for $19.99, instead of wasting your 20 bucks on a crack pipe , and KY Jelly for those lonely nights. Use it wisely and buy the "I need manners bible" and you will learn a wealth of information about something you have no clue about, except for all the myths you've read. I think you really need to learn better "people skills" and you might sell more of your POS books. From your posts I've read, you seem to "assume" alot, and that my friend is what gets people killed, or in alot of trouble.

93 VENOMIZED · 05-01-2002, 05:21 PM

This is the problem today, everybody has an attitude and takes things the wrong way. I never implied that everyone in here was dumb, just misinformed about oil qualities, just as I was. I was under the same impression that you had to change your oil every 3k miles, not true. Thats what the oil companies want you to believe so they make more money. Todays synthetic oils are far superior than convential oils, and have much longer drain intervals. Just because oil is brown doesnt mean it has to be changed. And BTW, obviously none of you took a minute to even check out the motoroilbible website, because if you did, you would have seen that it only cost $9.80 now. Just because you walk into a store doesnt mean you have to buy something. You guys need to chill, and not be so close minded to what you think is the only way. I dont find your smart answers funny, just ignorant. Peace!

To honest here guys, 93 Venomized brings up many good points about motor oil. I covered some of these in Mod Madness a week or 2 ago. Do a search, cause I don't want to get into the length of that post again

.

I'm curious 93VENOMIZED, why do you use a 0W30 oil. I have only seen that oil used in Northern Canada, Which even then a good 5W30 or 5W50 provides much better performance (IMO).

Although 93 VENOMIZED did come "unglued" rather quickly, I think some of you guys attacked this new member rather fast too.

Maybe we shoud start over again.

Welcome 93VENOMIZED. I hope your future posts are more pleasant than this one.

Just remember it is not good to show up and start preaching when you're fairly new. Members who have been here sometime and have a fair bit of experience themselves, like Mach 1 will get offended.

Believe it or not a poll done some time ago showed that the average age on this site is much higher than you'd think
