Shit, it may mean I need to redo ours soon.

LOL That 9000 mile photo I took at 62 mph was on a busy freeway merge, driving in a right-most lane that's about to end, between a whitehair in a Buick and a garbage truck. But, speaking of the F150 gas mileage - is it measured at the pump or calculated by the ECU?

Only 91+. It is a high-compression, turbocharged engine - it would likely kill the boost and retard the ignition if it ever heard detonation.

The obvious joke would be "I take the Fifth," but the truth is that in most cases I am a ~90-percentile driver (excluding driving in carpool/express lane when the rest of the traffic is jammed). The I-15 dips in that plot are in Utah (where speed limit is 80, and even the big rigs drive 5-10...

I started logging the gas pump numbers at mile 870; the odometer is incredibly accurate, within 0.1-0.2%. Here's the gas mileage record up to ~9000 miles yesterday: The total mileage in the log divided by the pump gallon numbers total is 14.0092 mpg. Everything above 14mpg mark is country roads...

IIRC, they claimed 15.5 - which I just couldn't see achievable, so 14 is okay.

9k miles in 160 days of ownership... I need to drive my Classic more.

Read again, 370kmi. The truck's at 387kmi now.

from the standpoint of average under-axle clearance across entire track.

Before the $76k Grenadier, the choice of LR4 and 385-kmi Classic pushed us to rent a Suburban or a Tahoe or a Wagoneer on a few recent cross-country trips. Wagoneer was the oddest of the bunch - with ridiculous gas mileage (22 mpg on a 2800-mile trip), but it earned nobody's love. Compared to...

I am sure they gave the big boys slightly better stuff; but, since in 2010 LR wasn't even aware of the issue, I don't think early ones had anything different. FWIW, the frequency of 2.7/3.0 diesel crankshaft failures overseas for D3/D4/RRS is about the same.

IIRC, I took the LR4 in for chain tensioners around 155kmi, owned the truck since 17kmi and changed oil at about 5kmi intervals. I don't think one's got ear good enough to hear chain clatter over high-pressure fuel pumps - their sound is dominant, in and out of the cabin. Mine didn't make any...

Chain: I know of two mechanically-inclined and attentive people with well, meticulously, maintained LR4 and RRS, who experienced a timing chain skip - in one case, the engine was done in, and LR4 sold for scrap value. In another, somehow, the engine survived but required about 8k in parts and...

I now have a tally of two 4HP22s going tits up in 95 Classics, both behind 3.9s, one - at 220kmi, another - 370kmi. 32% more torque than a 3.9, in a vehicle that's 12% heavier... What could go wrong?

Basically.... There is no warning whatsoever before timing chains skip in 5.0 (3.0 is the same, for that matter). It runs beautifully, and then in a split second it's not worth its weight in aluminum. I caught a cam-related code in our LR4 completely by a chance - while showing the tester to my...
