You know, those oils that didn't even exist when the the spec was concieved...duh.
You guys conveniently forget or disregard 90% of my posts, instead fretting about people's reputatins and, lol, "feelings".
The pathetic cost analysis Trajan attempted is quite awkward, as a 5000-6000 dino oci has far more of a safety cushion than the extended synth intervals. This is expecially true if you look at the matching TBN of the two oils. Same TBN, 1/3 the cost...by Trajan's tortured logic has it as a more costly approach.
The most tortured logic is by far Trajan's refusal to observe BMWs recommended change intervals, rather HALVING them to the point dino oil would work fine at. That's brilliant reasoning (not) and basicly represents the opposite of what this forum is all about.
One more thing, you don't pay for oil changes, BMW does. That's hardly an objective starting point for you. What I don't get is, BMW changes it at 15k, but you want it changed at "7500", who pays for that? I mean, why bother, since the examples of 15k engines that you are so fond of look so pristine?
Used BMW purchase at a Ford dealer, "priceless".
I take it you own this sweater?
