Email reply from Mobil. I don't know exactly what their base stocks are but it doesn't seem to be primarly Group IV.

 

That's a fair statement to make for some of their blends. The 0W-40 I think has a good amount of PAO, because a G3 couldn't maintain that VI without a higher pour point and so few VII's, but who knows exactly besides XOM. It doesn't matter. The PAO base stocks don't need the VII's a G3 oil would need, hence the pour point values being a product of their PAO. How much is left to others is a matter of required weight and needs. All PAO oils have to be mixed with other base stocks, either G2, G3 or G5, in order to hold the add pack. It's by nature of the oil. There is no magic cut-off point of base stock blend percentages to say one oil is a "true syn" or not. If it uses a PAO or G5 base stock, and M1 does, it's a synthetic oil. If they use a G3 base for add carrier, and some G5 AN for ester solvency and seal swell (maybe even for PPD use, but prob not) then it's a pretty well rounded mix, if it works. They don't use a G2, so it's not a "syn blend" and it's not a straight G3 like some others.

22 bucks for 5qt is a good buy. Ever consider GTX if you're not tracking the car and doing 4500 mile OCI? Great results.

As I understand it, BMW uses 0w 40 Mobil and "probably" requires them to use a better base stock. I've read that 0W 40 is still a grp IV type oil.

I suppose I could use most any oil being NA and running a 3750 mile change. The thing I like about Walmart is that they offer the oil in 5 qt jugs vs the useless 1 qt containers. I can dump my old oil into the empty 5qt containers.

Could be time to switch back to GTX if they also have the 5qt container versions

 

+1 with GTX. It was my prefered choice of regular oil before I went with Synthetics oils.

 

oh stop it with that! b.s. one test, one time, does not mean its crap oil. i think more people agree with me on that.

 

What is your reasoning then or basis for it making you the "happiest"? All 3 of the royal purple oils tested have done poorly. Do you have a UOA to post to counter this information?

 

Why ice skate uphill? At that price, I'd would not want to see even 1-2 bad UOAs. Especially when there are others in teh same price or cheaper range that perform better.

 

Guys, I used to buy into all the Redline, Amsoil, Motul, ect... Group V mumbojumbo. The fact of the matter is that just because these companies use better basestocks really means nothing. Companies like Castrol and Mobile 1 have research and development budgets that make companies like Redline and Amsoil look very small. I truely beleive now after reading about this subject for quite some time that the additive package is what makes the difference.

 

Just because a company might be a behomouth, doesn't make their products superior. These large oil companies can't manufacture a product as good as AMSOIL synthetic motor oils are, or else the product wouldn't sell very well compared to other motor oils as the price would be so high. Consequently, synthetic motor oils that are price formulated can be easily outperformed by synthetic oils that are peformance forumulated, like AMSOIL.

Bi-Tron > Amsoil
mms://lastream001.galaxytelevision.n...rageAmsoil.wmv

 

Sorry but Bi-Tron does not own Amsoil. Bi-Tron is a additive, like Slick50. Amsoil is still better than most oils in the market. And Bi-Tron can help any of those oils work better. Now if Bi-Tron was a oil all alone, then I would say what you did, but since it's just a additive, no.

 

I wrote that in regards to what Still2Slow wrote as far as the principle of additives goes:
Cost wise, and as explained in that vid is that any motor oil + bitron > amsoil alone. And at a corrected standpoint, any motor oil + bitron > amsoil in the performance aspect.

so I guess if your opinion is that amsoil is the greatest oil on the market, then amsoil + bitron would be the best combo in whomever's opinion, and whomever wants to induldge that far.

 

There may be some truth there, but unless you know the actual statistics it's only conjecture.
I do know for a fact, before Mobil merged with Exxon it was the 5th largest oil company but had the largest percentage of budget dedicated to research.
And considering they did produce the largest consumer market for synthetic lubricants way before any other major oil company that should not be surprising.
I don't have the stats because I am talking about developments taking place back in the late 60's and early 70's.
With some research it should not be too difficult to find. Being an old fart I remember reading of their research during that time, and certainly have no reason to lie about it. (no vested interest in any lubricant company and no stock in Exxon...LOL)
Does that mean it was the best lubricant? Maybe in some ways yes, some ways no.
Know one really knows except how it relates to specific lab results. Objective lab tests? I guess we have to swallow that too.

What continues to be missing in ALL this discussion is what difference this makes to the average driver of a G35 or any car/truck for that matter.
No one knows.
....show all the charts you want, and make all the claims you want.
Folks using factory recommended lubricants and servicing their vehicles at regular intervals should not experience any problem related to the 'brand' of oil they use.
Don't believe that? Show me the proof, not just lab results, and what 'feels good to me'. If you are happy with what you use, keep using it!
Nothing takes the place of peace of mind.

 

That one test doesn't show anything other than its a friction modifier. There is no evidence on how it actually performs in an actual engine, where heat, viscosity, long term stability, sludge resistance ect come into play. The design of an oil isn't solely to have the lowest friction

 

Well that might include anyone that wanted the best protection for an engine worth thousands and thousands of dollars. Have you priced a new engine lately? Be prepared to pick your jaw up off of the floor. The additional benefits of improved fuel economy, more power, lower emissions, easier winter starts, an engine that runs, "like new", for a longer period of time, cooler engine operating temperatures, lower maintenance and repair costs, using a made in U.S.A. product as opposed to blood-stained Middle East oil products, etc., are all benefits any motorist can enjoy.

Be that as it may though, pour in oil additives upset the delicate chemical balance of a motor oil and can have unplanned and negative affects. Pour in oil additives will also immediately void the AMSOIL product warranty.
