Up until now I've always used Mobil 1 5-30 in my 94, but I've now found some Castrol Edge 5-30 synthetic for a much cheaper price, any reason why I shouldnt use it?

No, I say, but this topic usually has NO SHORTAGE of opinions.

Castrol Edge is a very good oil also,can't see how you could go wrong

You'll be fine with that oil.

Correct spec fluids and proper maintenance schedules are much more important than what "brand" you use.

..Todays major brand oils are so close in quality, and so superior to oils made 20 years ago, that your splitting hairs comparing one to another...WW

I use AMS Signature Series 0W30 with their EA filter with up to 25000 miles between changes. When my neighbor changed it on my Aurora he couldn't believe how good it still looked.

i´m using castrol edge with no problem.
as you can see on the photos, it´s US made and labeled for latin america´s market.
i suppose it´s the same oil you found.

agreed...

any synthetic is a GOOD oil.

The 1st 10 years were the "test" period, waiting to see the proof in the pudding so to speak.

Now, after so much evidence and "proof' of synthetic quality and virtually NO Brand, "bad mouthing" of their synthetic, I comfortably run up to 6 or 8000 miles between changes, BUT I DO change filters every 2000 miles.

It was baby steps for me.

1st it was the step up to 3000 miles....then 4, then financial crisis forced me to take the leap to 6000 !
No ill effects. The comfort zone comes in fresh filtration where the real damage is done in engine lubrication. Old, dirty filters almost certainly send the majority of the oil thru by-pass instead of getting ANY filtration, so a new filter helps assure you that there is more going thru filtration instead of bypass due to a clogged, dirty spin-on filter.

That also means that you get 1 qt of fresh oil each 2000 miles when changing the filter....method to the madness.

I read a study conducted by Consumer reports a few years back. They tested name brand synthetic oil against regular, non-synthetic oil in NYC taxi fleets. They tore down and inspected engines after about 100,000 miles and found no discernible difference in wear. At the end of the article they only recommended synthetic oil for engines that were used in extremely abusive situations, like racing. High, sustained revs and temperatures.
I would wonder if the average Corvette owner is just wasting money by using synthetic at all. I don't even recall if the owners manual in my 89' even recommends synthetic oil..... I know newer models suggest it.

If I understand correctly, L98 is a standard-compression motor that had a factory oil cooler. So it would probably be fine with a petroleum-based motor oil, assuming it's not raced/abused or driven in dusty/severe conditions.

I also understand that, under certain conditions, the LT1 was designed to run much hotter than "normal operating temperatures," and the LT1 has no factory oil cooler. Add the fact that the LT1 is a high-compression motor, and a Corvette likely gets more "spirited" driving than the average car, I think it's very important to use an approved synthetic oil in the LT1 and follow the factory-recommended OCI. 5 quarts of Mobil-1 5w30 costs $24 at Wal-Mart. Online, you can get premium oil filters (Wix, Bosch, Mobil-1, PureOne) for $9 or less. That is some very affordable maintenance.

I have always wondered about changing filters in the middle of an oil cycle. Sure if I'm running 15,000 mile extended intervals in dusty conditions, I would not wonder. But a maintained engine that's run synthetic will be pretty clean, and if it's run in normal conditions, I can't imagine that so much stuff from combustion and intake air would be generated in 3000 miles (~half cycle) that a premium filter would need to be changed. Maybe someone can enlighten me.

I agree with the above sentiments, but as cheap as oil is, I just can't let it go 5-6000 miles. Mine gets changed every 6 months which is usually about 1000 miles for me. $60 a year, and the fun and satisfaction of changing the oil. That's cheap fun and insurance.

WW7

You could probably resell it as "slightly used oil" .. Plus, it's not "Cheap Insurance" , changing oil at 1000 miles is just wasting money........WW

HGUNHNTR

It's not a waste to me at all. I can afford $60 a year. I don't drive the car that much, and detergents do break down sitting in the crankcase. You don't really need to worry about my $60...I got it covered.

HGUNHNTR

And sometimes it's about minding your own business about how other people spend their money.

HGUNHNTR

No problem. It's *than* not *then*.

I'll continue changing my oil at the intervals that I choose, regardless the comments from self-righteous "oil change professionals". :pound:

HGUNHNTR

*you're* LOL!!!!

Chad30021

I remeber the first time I was butt hurt and had nothing better to say HAHA

Take it with a grain of salt if you dont was his opinion then dont comment

EDIT* Excuse me I mean DON'T (note the apostrophe)

HGUNHNTR

You can keep your opinion as well.

That's *remember*. :thumb:

HGUNHNTR

It's *than* not *then*. Also, I very much enjoy changing oil, and have yet to discover any possible negative from having my oil be "too clean" too often. I don't care about money, I care about the car.

HGUNHNTR

Absolutely. It's an excellent indicator of intelligence.
