Please help locate UOA results for the Vette LS7 engine. I cannot seem to find any. Meanwhile, many folks have stated they are leveraging these UOA results for selecting their motor oil.

Just trying to do the search, going back 3 years, using the kewyord LS7 and no hits. Then put in corvette and still no UOA results pop up.

Where are they posted?
 
Sadly, there are NOT a lot of LSx engine owners on here, let alone LS7 owners.

S***, there are barely any domestic nameplate owners on this site!!
It must be all of the domestic bashing that is not only tolerated, but seems to be encouraged on here.

There are some LSx truck UOAs posted but I can't remember a single LS1,2, and especially an LS7 on here but it would be interesting to see.

Off topic, where in So Cal are you located?

My LS2 is on here. The search feature leaves something to be desired.

Ls1 in my 99 SS camaro. Never done a UOA on it. Never felt the need to.

And about the domestic bashing I just laugh about it. I know whats good and whats not and you will never find a non domestic in our driveway.

For example tell me one foreign truck that will stand up to daily abuse of heavy towing and hauling? Tundra or titan? Nope they are JUNK compared the the trucks the big 3 make. This should get some guys fired up.
 
Come on now. There is no more domestic bashing than there is import bashing and there is no more Mobil bashing than any other oil. If you can't deal with contrary opinions just go somewhere else and surround yourselves with people who agree with whatever it is you already think. If you want to read lots of opinions, some of them very knowledgeable, and learn something, this is a good place for it.

In the meantime try to at least be somewhat respectful of the original topic when you post.

You are going to see much the same signature as the lower end truck engines!What where you hopeing to find or looking for in terms of the wear signiture of the LS7 engine?

There are four years worth of UOAs on this site posted from my LS1 Corvette. Just do a search under 98 Corvette and they'll come up. I've posted at least two UOAs per year since I got the car in August 2004.
 
I have an LS7 but not putting a lot of miles on it. Just changed over from factory fill to Amsoil 5w-30 and amsoil filter. At this point I would expect a minimum 6 moths before I can do a UOA but if I don't forget, I will get one and get a UOA onboard for the LS7.
 
Well first if someone see's my post's as bashing it is really disgust and disapointment. Nothing makes me more upset then to see my fellow Americans do the same stupid stuff over and over and over again when I know good and well that we have the capacity to be global leaders in al area's of science,technology and production. So if I bash it is only because it makes me sick that I have to buy a Toyota to get the type of enginnering and materials in my powertrain that I feel I deserve for my dollar!

You will also note that I do give praise where I think it is deserved as well and have always praised Ford's modular design and their I6 300. I have always give lots of praise for the 4.7V8 and 3.7V6 and 5.7 Hemi and the 3.5 HO that Chrysler have had on the market. I never say anything that I do not think is fair and honest and unbiased. I have also consistently comented on Toyota's quality slipping int he last 15 years especialy in reguard to their USA operations! So no one can say I am not fair! I call it like I see it. Obviously I do not expect everyone to agree with me but that does not mean we can not all respect each othrs right to have an opinion. My idea's on automotive industry have nothing to do with my politics at all.

The area's in that block in question that have significantly better materials then the rest of the fleet but lower block flex is still an issue even with the different casting. The internal harmonics are still very close tot he rest of the series.While the valve train materials are lighter and better I doubt it will make much difference in terms of wear since the basic geometry is the same and the ramp angles and vale loads are probably more radical. The bearings and bushings and ring materials are probably close to the rest of this engine familys so that too should produce simalar wear numbers. So unless the bottom end is massively stiffer and the ring,came and bearing materials are radicaly different we should see simalar signiture. Block flex is the key to wear. If you have a stiff block and use high end materials wear is always low.
 
Terrific post. I personally have tended to drive imports but have a lot of respect for certain domestic designs, for example the GM 3.8l V6 that has done so well in so many cars, the Ecotec engines, that seem overall very good in many ways (not up there in terms of NVH, by the way), a lot of the work GM has obviously done to improve fuel efficiency across the board, which is largely un-noticed, and the excellent technology put into the Corvette.

At the same time I find fault where fault is due with the imports, for example Nissan's apparent slide in overall quality over the years, the unfortunate problems that Honda has had with many of their auto trannies and the even more unfortunate problems Toyota seems to be experiencing in quality in many of their vehicles (Tundra, Camry V6, possibly Tacoma).

We have a fairly level playing field now between the Japanese, US and European manufacturers, and really nobody has a any good excuses for making a car that is less than very, very good. I still see the domestic manufacturers' biggest problem not being quality and reliability so much as product appeal: they seem unwilling to make vehicles that are absolutely the best possible, without compromise, whereas that seems to be the driving force behind the world's best car companies, which in my humble opinion would be BMW, Honda, Toyota, Porsche and maybe a few others.

That is not bashing and nor was anything you've said, JB. If some thin-skinned people want to take offense at my observations of what I perceive to be the truth, that is their problem. Just remember, the domestic industry will not thrive because of people who automatically buy American, it will thrive (if it does) because of people who were willing to buy the best, therefore forcing them to compete at that level.

Especially with the weak dollar, the US industry will have the best chance, in the next few years, to compete that they have in my adult lifetime, and I really hope they don't mess it up.

As for the original topic here, the LSx seems to have been an unbelievably good engine, an excellent example of what the domestics can do right. I still hate to read comparison tests where the 'Vette is always said to be less of a driver's car than its major competition, and I know it's true. The British used to have a saying: "Big engine, big tires, big deal." But the Corvette is undeniably a world class performance car and kudos to GM for it.

One of the best things about the Corvette is that it's got performance close to that of the exotics, at a fraction of the price AND they are cars you can drive everyday! It's not unusual to see Corvettes out there with 200,000 miles on them and they still run like new.
 
Thanks for all the responses!!

Patman: Based on my short experience with BITOG, I know I am right when I state that you are one of the better contributors on this site. You deserve a thanks.

I am in Laguna Niguel, in the OC - Monarch Beach.

As for oil, based on my research - the daily driver Z06 would do best with a 4718M spec'd oil, and probably something like GC 0W30 for the occasional track weekend. Would make track events a bit more expensive - but it keeps life simple; mileage and wear optimal.

A 6 speed Vette is one of those cars I`ve always wanted to drive. The Corvette is definitely THEE BEST American made car ever!

I`ve always considered the Corvette to be an American exotic.

The Search function on this site does not work for three-letter words. Use a search engine if you want to look for LS7, or Amsoil product codes, for example.
 
Pushrods are for cavemen!

On that note today all three domestic car manufacturers had their bond ratings reduced to JUNK.

As a liftetime resident of the Detroit area it makes me sick what the money hungry executives and corrupt unions have done to the American car industry. I've watched the slide for years.

From a technical perspective the American cars companies are light years behind the Japanese. They'd rather pay their executives and keep the Union rich instead of invensting in R&D.

Honda is leasing fuel cell vehicles in California this summer. A reporter asked GM how long it would be until they were ready to do the same. Their reply was "8 years!".

8 $%&^#$ing years! How $%&^#$%ing stupid can you be to get 8 years behind you competitor in R&D?

YES, HE IS!!! As well as on ls1tech.com!
Probably the most fair and unbiased member, let alone mod on here (he has owned import nameplates along with domestics and has stated the positives AND negatives of each!)

Most of the posters on this thread, albeit being import nameplate biased, are not that bad and have at least a trace of 'centrist' attitude/thought between the makes/company's countries of origin, etc.
But there IS a decent sized faction on here that is almost MILITANT in their abject BASHING of ANYTHING/EVERYTHING GM/domestic, etc. ANY and EVERY chance they get, even when inappropriate/off topic, or uncalled for!!
I'm not naming names, but we know who they are (some have not posted in a while, THANKFULLY!!!).
