Did I? Please specify which OEMs are doing this. But also specify just how long is the vehicle life that they certify to the US government?quote:You forgot once again that many OEMs are advertising lube for life tannies and difs already.
And just how permanent are these "permanent" oils? Do they tell you that it will last 150K miles like SynLube does? What do they really mean? I suspect they mean the useful life of the vehicle that they certify to the US government. And you might be surprised at the estimates. Especially in light of the light engine oils OEMs like Ford are using.
I'm not so sure the OEMs want us driving one vehicle 200K miles. As with the Yaris, they may be specifying "permanent" oils because they don't want this.
I do not contend that lubricants that last the life of the vehicle (as an owner would expect)and beyond are unknown. In fact, even though they didn't advertise it, Ford installed an axle in my Ranger from Dana that used an ester-based lubricant that Miro told me about to reduce warranty costs on differentials. He said it had a service life of about 750K miles and that there was no point in replacing the lube though I eventually did anyway because I replaced the OEM limited-slip with a PowerTrax unit.
If you will look at previous posts I've written, you will find that I have never contended that SynLube is a magical substance that is a total secret to other lube providers. The components of the SynLube formula are available to anyone who wants to make a SynLube competitor. But it's all about the money and dino oil is a money-maker. The dealership where I bought my Ranger has a service bay dedicated to oil changes and you can bet that that every effort will be made to sell that customer other services while he's there. You'd have a very unhappy dealer if Ford brought out cars that didn't need oil maintenance services.
And the Murano incident that you cite as positive proof that SynLube doesn't work just doesn't stand up to scrutiny. The guy was screwed by the dealership that just assumed that the SynLube was full of sludge. If they had acted properly and recommended an oil change, the person would have had a chance to tell them that the oil's color was normal. And from the guy's comments about his wife, he was alsos bullied into not using SynLube again. We have no hard proof that SynLube was at fault. And that's what you would say if the oil you favor had been used, not SynLube.
Finally, TEMPEST, I am spending a great deal of time answering your posts and I just don't have any more time to waste. If you were truly interested in knowing about SynLube (whether you intened to use it or not), it would be one thing but you're certain that we've made a huge mistake in using SynLube and you're going to tell us that until you're blue in the face. Your mission is complete. I and others are fully aware of your views.
You are not going to change my mind and I know I'll never change yours. So, with your rejoinder to this post, know with pleasure, that you will have the last word. But also know that you have not presented anything that amounts to a substantive case against SynLube and when I purchase my next ride, I will consult with Miro about my lubrication maintenance program for that vehicle and install SynLube where he thinks it useful.
