Originally Posted By: mva If the claims by Castrol, Valvoline and QS(Sopus) were false, Exxon would sue all three in a heartbeat. How can they prove the test results are false, when the result details are not even published? Can they prove that the current Mobil 1 5W-30 meets specs? Yes, they...

Originally Posted By: Bill in Utah IF Mobil HAD a case, they SUE them to the end of the world. Just for Marketing purposes. 99% of the public knows nothing about the Valvoline claims against Mobil 1 and at my Walmart M1 is still flying off the shelves. If XOM sues them, it is just free...

Originally Posted By: Bill in Utah And BOTH of them are going to take a risk on having big bad Mobil sue them to never never land with no IRON CLAD FACTS? ExxonMobil probably cannot sue anyone for the following reasons: 1. Valvoline is small company (relative to XOM) and does not produce or...

Originally Posted By: badtlc The quoted material says Valvoline AND!!!! and independent lab ran multiple tests. It doesn't get any more clear than that. Yes, they ran multiple tests, but they don't say how many time Mobil 1 failed the test, and how exactly many times they ran the test. Why...

Originally Posted By: StevieC I heard that Amsoil SSO 0w30 is really like a thick 20wt and not a true 30wt once put into service. Can one of the Amsoil dealers confirm? I would think Amsoil 0W-30 is closer to a European formula 0W-30, such as German Castrol 0W-30 which are ACEA A3/B3, and not...

Originally Posted By: OVERK1LL The one myth that apparently seems immune to death is the UOA can tell you how your engine is wearing one..... Yea. That's because a UOA cost about $25.00 and an engine tear down costs about $2,500.00.

Originally Posted By: Pablo SteveC was just rambling - totally different than the site itself promoting something. Wow, no wonder people have big doubts about you. I made my original comments about myths to a newbie who is trying to make decisions based on what people post on this forum. SteveC...

Originally Posted By: StevieC I agree with you that even Amsoil cares about profits and is greedy just the same as the next company is, but don't forget that they are a smaller competitor with a lot of non-licensed oils that is trying to gain marketshare and the only way they can do this is by...

Originally Posted By: StevieC Not that M1 oils aren't excellent, but I'm sure they have made major changes since then. Plus with all the corporate greed squeezing going on it has to make you think that compromises have been made with all oils & companies in the name of profit no? Yesterday I...

Originally Posted By: Audi Junkie No, the chart does not make sense because 10w-30 is thinner than 5w-40 at below 0f and all temps. Are there any conventional 5W-40 oils, or are they all synthetics? That might explain the paradox.

Originally Posted By: mazz3 I usually do watch them and give them oil and filter at a oil change joint. I just went to the dealer for the first one for what ever reason. It seems to me the dealer needs to be reined in by the manufacturer. Be professional and stick to the standards that are set...

Originally Posted By: mazz3 Another question; would the manufacturer accept 0w-30? It's not specified per se. No, they cannot recommend a different viscosity than what the car was certified using for the EPA fuel mileage calculations. Please do not make me repeat this again. But "recommending"...

Originally Posted By: sayjac Quote: The warranty will not be voided if the dealer uses 5W-30. And you know this how? Because the authorized dealer installed the 5W-30 oil, and they know perfectly well that the 5W-20 is an MPG issue and not a engine longevity issue.

Originally Posted By: mazz3 When it came to issues, he was pretty vague. He talked about turbo's smoking and having to go to 40w with those... The manual says 5-20w, except if you're in Mexico and can't find it than use 5-30w - it says that in very fine print. I plan on talking to the rep...

The article says pre-95 not good with synthetics. OK, there was some point in the past when synthetics had a problem with older cars, and I am not sure I would switch to a synthetic on a pre-95 either, even though I strongly recommend synthetic for new vehicles. The only exception would be that...

The warranty will not be voided if the dealer uses 5W-30. The auto companies are under extreme pressure to increase fuel mileage and must meet increasingly stiff CAFE standards. Obama just accelerated the implementation of CAFE standards in upcoming years. So the automakers must be very careful...
