Originally Posted By: KL31 Nice, almost 11,000kms and still decent TBN level. Will you go further next run? Most DI engine with fuel dilution tend to thin the oil but this seemed to take it very well! Because bio-based esters are not derived from petroleum feedstocks, they are essentially...

Originally Posted By: nthach It's a fancy X5(or X7 if BMW made one). Uh, no. This is built on the same all aluminum space frame platform that the next generation Phantom will be built on, which is not based on any BMW platform (unlike the Ghost and Wraith).

As I suspected, it's going to be a "high body" Phantom with AWD. Click Here for the full press release.

The truth is, any good pillow will achieve the same results that My Pillow does. The problem is finding a truly "good" pillow. If you don't have allergies, then down is the ticket. And the quality of down is important, because you can get cheap down pillows at department stores that are no...

Fourteen years ago today I made my first post on BITOG. It was about Shell's then new Rotella synthetic 5w40. Click here to read it. A lot has changed with motor oils since then. How long have you been on BITOG and what was your first post about?

Just from my own observations, I'd say (at least on the C6 with the LS2 and LS3 engines), the Vette runs higher oil temps than a typical passenger car or light duty pick up. Even when the outside temp is a relatively mild 75F, I see oil temps of 230F+ on the Interstate with cruise set at 70 mph...

Originally Posted By: Nate1979 Manufacturers since the dawn of time has always recommended thicker oil for high load situations (track, towing,mountain driving etc). This is nothing new yet people get surprised at this? Even my lowly 2010 Subaru Forester says this. Absolutely not true, which...

Originally Posted By: bdcardinal I don't think this is new for 2016. Ford recommends 5W50 for my Track Pack Mustang as well as the GT350/R, Boss 302, and GT500s. The year has nothing to do with it. And last time I looked, Ford and GM were two different companies. My point was that for years GM...

For decades, GM owners manuals (including for the Corvette) have specified 5w30 with "warnings" not to use 10w40, 20w50 or other weights. Look what is in the 2016 Corvette owners manual. Is GM finally admitting that under certain conditions, something thicker than 5w30 is required?

Originally Posted By: deven ^^What causes the Oxidation and Sulfation numbers to skew so high in the RLI formulations? The car only has 33,154 miles so what kind of cleaning is RLI doing in a fairly new motor that the TBN is taking such a hit?? Direct injection engines are notorious for ring...
