any one out there using regular oil and not synthetic?

 

Personally, I would not even consider using anything but a synthetic oil meeting GM Standard GM4718M. Following from the 2003 Corvette Owner's Manual, Section 5, Service and Appearance Care:


Engine Oil Capacity:

Both the owner's manual and GM Service Manual say approximately 6.5 quarts with filter. However, much will depend on how well the system was drained when removing the old oil.

 

To the best of my knowledge, no non-synthetics meet GM Standard 4718M and I wouldn't consider using one either. My Z06 usually took 7.0 quarts with a filter change, but everyone's car seems to be a little bit different. Somewhere around 6.5 to 7.0 quarts is average.

 

Some of us may look like idiots You do not want to put petro based oil in your car, not even synthetic blends.....if money is a problem and you cant afford the right spec for oil, you should sell it.
Car requires 6.5 qts. 7 may be use if tracking the car.Mobil 1 full synthetic with the GM standard printed on every bottle. GM4718M
5-30 is recommended but 10-30 can be used especially in hotter environments.

 

My god man. Are you serious? I cannot believe you are even considering a non synthetic oil. I agree. If you can't afford it, get a mustang.

 

Use any oil that has GM4718M on it....
Don't use any oil that does not.
5W30 is best but 10W30 can be used between not and the time your local temperature goes below 40

 

 

I am gonna throw this out there and see what you guys think! I wonder just how much GM.....REALLY..... wants our Vetts, or any cars from any company, to last? This may sound crazy but these auto companies are not in business to show us how to make our cars last forever!, they are in the business of selling cars! Maybe they give us info, such as the kinds and viscosities of oil, to let our cars get a bit past the warrenty. Maybe just enough to even get through a possible extended warrenty, and then blow up! I want to think the best of GM but business is business!

This has nothing to do with the topic of synthetic or non syn oil, and I too will only use what is rcommended by GM! It's just something that crosses my mind once in a while. A little food for thought!

 

None of the non-synthetic oils meet GM Standard 4718M. You should use either Mobil 1 or Amsoil full synthetic oils meeting this standard.



In 2005 an API of SM was introduced which has lower Zinc and Phosphorous contents of 0.087 and .080 respectfully compared to the 2001 API of SJ & SL with Zinc and Phosphorous contents of .11 and .10 respectfully.... (1996 SH: .13 and .12)

Due to more stringent emission requirements, the oil maufactures have been limiting the content of Zinc and Phosphorous additives to keep emissions as low as possible while not damaging the catalytic converters. This change will lead to increased engine wear, especially to the valve train and cam shaft of the older non roller engines. Zinc and phosphorous reacts with cam lobe surfaces creating a chemical coating to prevent wear.

 

And TWA 800 was really shot down by a missle too, right?

Try again.

 

That's what I'm running down here in the Sunshine State.

 

So you think I am WAY off base on my thoughts? If so, then you must truely believe that the auto companies want everyone's car TO last as long as humanly possible? You might want to rethink that. We are talking about money here. I suppose we, the USA, can't make a car that gets better gas mileage either!

 

Yeah, I can speak with some authority on this... I am very proud of this car....we put alot of technology into this car,,,, longevity is a prime example.. This car was throughly tested to 200,000 miles.. the industry standard is 100,000 miles when the schedule maintenance is followed... An Ls/X engine can regularly see 200,000 miles plus... Thousands of dollars and hundreds of hours were put into the oil life monitor system to help keep your oil within the specs to get you past 200,000 miles.. the specs are specific... Last time GM built an aluminum alloy engine was in the 60's.. life expectancy was right around 60,000 miles... Automotive technology has made quantum leaps in the last 15 years....The consumer is a recipient of this technology.. I am proud to have been a part of the design and inception of the car... There is No such thing as designed obsolecence...GM builds car with reliability in mind.....
Are the cars perfect??? Hell know. If they were, you and I could not afford them... this is a 100,000 dollar American sports car with a 50,000 price tag...
Failure of components is rarely the fault of GM.... its usually the fault of the suppliers who manufacture our parts.... WE pressure them to commit to a price, and then they try to figure ways of making a profit, they want GM's business... the car is a credit to to project mangers keeping it within budget and delivered on time.. Many suppliers lose our business because they do not keep their end of the quality agreement.. Many suppliers lose their ISO status because they do not comply with their own quality standards.,..
To answer your question.. The corvette is designed to take you 200,000 miles plus... A feat not easily duplicated.
Dont see too many mustangs bringing 300,000 dollars at a Barrett Jackson auction...

 

Point well taken! I honestly do not think my ststements hold true in the Corvette's case. The car is a marvel and every magezine says so. It is an honor and priveledge to own one and I feel extremely luckey to have one!

However, We are still taliking about big business and big money! I am not knocking the USA! I will buy nothing but American!! I do think though that ALL companies, excluding their specialty cars like ours and other exotics, are making cars with $ signs in their eyes, & too much longevity in a vehicle is'nt a good thing.

 

No one looks into making a bad car..... there are so many things about manufacturing that the average consumer never realizes...
Ive tried to share some insider info and real world experiences with this forum since my retirement in 2001...
sure its all about business and the dollar... But credit is due to designers and managers to do the best job possible with the money they are allotted..
The car is built with a designed budget... ( A target market..) with built in profits...
Once the market is established, the budget is set.. it is then the job of the project mangers and the designers to deliver the car...
I am proud to say the car was delivered within budget and on time....
sometimes decisions are made that a few extra dollars could make a difference in the quality of a part.. but keeping the car in budget is very very important.. if each project went 10/15 % over budget the car would be out of the target market.. these are the complexities of budget management.. you only have a certain amount of money to develop and deliver a certain design. I was involved in a design, of my seven that are in this car that would have cost an extra 1.5 cents a copy...it was rejected as too expensive...every one wants more money for their projects..this is why the car isn't perfect... Not because it was designed in...

 

I've had mine for 4 months, it's everything I ever thought it would be and more. Dream car @ 24? Crazy. Nice Job, Evil, I'm thoroughly impressed.

 

Yup. True words. And this conversation has not even begun to touch on the (to me at least) obvious aspect of product/quality image and it's direct positive or negative impact on the buying public. This is not rocket science here. You build a crummy product, YOU LOSE! PERIOD! EVERY TIME! Basic Marketing/Manufacturing 101!
"Planned obsolence" is kinda like this oil company gouging debate that's recently being regurgitated again for the umpteenth time. Some urban legends will just never die because some folks absolutely love or believe in conspiracies, etc.

 

I agree with everything you said & you said it the same as Ive heard it before.Thats the part about suppliers trying to meet the standards set forth & still make a profit.People have to remember,this car is relative priced to the first one that I had the priviledge to drive & drag race,The 64 coupe.While I loved the shape & style of that car,it was a far cry from what we have now.The fiberglass is better & alot of it is palmers or plastics.Think of all the extras on this c-5 as well.Also remember what happened to the Ford GT.I believe this car could disappear to if people just complain all the time.I bought mine used & have few problems at all.Sure there are afew things I whud have done different on the car,but all in all,theres nothin like it,is there???

 

allme you got to much time on your hands with that comment.

Though I do believe GM made these FOB break with a timer built into the chip.

 

Why is everyone getting so offended? I did not say that I know this to be fact, I just said that it could be possible. There is so much corruption in the world and in big business, and money rules all, you just never can tell!
