well, when you realize this stuff goes for 5,000 miles easy and holds up better than most oils after 3,000 miles, it's not too bad. you basically get 3 oil changes for the price of 2. i mean shoot, mobil 1 is more expensive than GC at autozone, and you don't have to pay for the gas to drive there only to find out it's outta stock

 

Sorry, beat you to it

I changed my oil back in March and had a test run. Well, since this was the first batch of the "new" formula I put in I decided to drain just enough oil out to get a test done last week. Below are the results I just got back. Compares to the last oil test I had done on the old stuff back in March.



I drive my engine very HARD too. While it does not get a ton of miles overall it gets driven hard 90% of the time.

 

good thing you beat me to it. I had to add a quart yesterday and all I had left was the green stuff. So I my sample wouldn't have been 100% accurate.

 

wow, impressive. if the people who do oil analyses tell you to run the oil even longer next time and your engine looks 22,000 miles newer than it really is, you must be doing SOMETHING right. this is why i pimp GC.

I think you may be misreading the report. The report does not say these averages are what a motor should look like after 4200 total miles. They are saying this is what the OIL should like like after being in the car for 4200 miles. It does show me that the new formula is every bit as good as the old formula based on these numbers.

The reason the other reports I have had done on this car don't show on this sheet is because I renamed the unit number as I could not recall the last one I had done.

 

yup, i definitely misread haha

 

ttt for information's sake

 

after reading this post last night i was in need of an oil change so i went to autozone to see if i could find this german made stuff!

well it didnt say german made but it did say "eurpion oil" in red!! it also said maid in germany on the back and it was imported to wane NJ looks like the stuff!! almost has a green tent sorta

 

well, all I have to say is I challenge anyone here to show me some cold hard facts such as the gamet of oil tests between this stuff and Amsoil to prove to me is soooo much better. I think you may find the opposite or maybe near equal, but saying something like " this is the best oil for an LS1, bar none" is purely subjective. I'm an Amsoil dealer and can get you guys 0w30 or 5w30 for much less then 8 buck a quart. I really don't see what all the hype about this german oil is all about.

 

See post #86

 

no one has ever done a test of amsoil vs. GC 0W-30 to my knowledge. amsoil IMO is overrated marketing hype. if you haven't noticed, amsoil never does straight tests with their oil. they'll put their 5W-30 against 20W-50's, 0W-40's and 10W-30's. their tests are tainted and they never go 5W-30 against 5W-30, at least in the ones i see.

no oil that has been put up against GC 0W-30 has beat it in wear analysis tests. factor in GC 0W-30 is $5.50 a quart - cheaper than mobil 1 and LOADS cheaper than amsoil - it's downright stupid to put anything else in your car. GC 0W-30 is $8/qt only at that website, which is intended for people who cannot find it at any autozone. plus, the shipping is free and there's no tax. factor in amsoil's shipping cost and you're still paying more.

if you'd like to conduct a GC 0W-30 vs. amsoil test and post the wear results, be my guest, i'd love to see them. just know that GC 0W-30 is completely unadvertised and very poorly marketed, whereas amsoil, you pay for disgustingly tainted advertisement ads and self-glorified praise. they constantly self-proclaim themselves as "the best synthetic". says who?

 

Below is a link to testing that was done between 10w-30's. Keep in mind that this is the standard AMSOIL synthetic ATM 10w-30 and not their better performing 0w-30.

well, you apparentally have jumped on a bandwagon here and have no idea what you are talking about when it comes to Amsoil products. See the link above, nuff said. It may not include the German stuff, but soon as someone decides to test it, I'm sure the results will be similar. Ever wonder why no other maker besides Amsoil can put '100% synthetic' on their oil? I'll give you a little clue; no one else is 100%, most still have parrifin/petroleum based stock in them.

 

yea but look at the oils they're going against? c'mon, they're going against $1.40/qt. castrol GTX. this is why i hate amsoil's tests. they go against more budget oils. they'll never post tests against GC 0W-30. that's all i wanna see since that's the only oil in question. all these amsoil done tests don't impress me. i want to see a test done by an independent 3rd party between the two.

 

To me ONLY an independent test counts. Oil companies performing tests against other oils and ther own oil is total BULL ****. What do you think would happen if another oil actullay was better? Either they would leave that oil off or lie about the results. Simple marketing 101. I'm not going to get into which oil is best because that is a debate impossible to win. I know which oil I use in my LS1 based on my own lab results and independent oil tests but I'm sure you guys can figure that out on your own.

 

+1, 100% agreement

 

The whole reason that the above link was posted was to show that AMSOIL does infact test their 10w-30 against other 10w-30 oils. You are 100% correct that GC is not on that report as it would be nearly impossible to include every oil but most important is the fact that it is not a 10w-30 which was asked for. AMSOIL usually tests against oils that they feel are most competitive, sales wise, in the marketplace.

The comment was made that oil company tests are BS and that you cannot trust them because that companies products always come out ahead. Why would a company report test that show them behind right. Well AMSOIL did just that, both in the test above and in the Motorcycle Oil comparison that you see here. Notice that they are not the best in every catagory. http://www.modernoils.com/media/pdf_...Comparison.pdf Remember that all these tests are done to ASTM standards and are repeatable in any lab following the same testing guidelines.

I am not here to bicker back and forth about this, just to provide accurate info regarding AMSOIL products so this forum can benefit from it.

 

i see everyone is using this in their ls1's...anyone use this oil in there LT1's? cuz the autozone down the street has 15 cases of this german castrol

 

patman uses the oil in all of his cars to my knowledge, even in his 4 cylinder. i say try it. it's some of the best oil out there, so you can't really go wrong IMO. if you feel shaky, run it for 3,000 miles and send it in for oil analysis. it's onlny like $25 or $30 to get it done. i intend to do it to my engine one of these times. the oil analysis will compare your oil after 3,000 miles to other oil people send in who own LT1 cars after 3,000 miles. i've seen oil analyses actually recommend people to run the oil longer next time since they're throwing away nearly new oil.
