Hi there,

I just got my hands on a v6S 2014. Wondering if I need to be extra cautious about the way I rev the engine particularly in Dynamic mode for the first 500 kms or so?

What measures have others taken?

Thanks!

 

With the Ftype R the manual provides break-in instructions and I would assume yours would too. I don't recall the details, however its straight forward concerning taking it easy up to certain mileage intervals.

Check out 'Breaking-In' in the manual, under Maintenance, p.134. (This was missing in the first edition of the manual.)

 

Hmmm.... Under Pg. 147 of my Owners Handbook, under "Maintenance." Also called "Running-In." (While I have the V-8, the Owners Handbook lists both the V-6 and V-8, so I assume the break-in process is similar for both engines.)

The Handbook calls for a 2-stage break-in process for 2,000 mi (3,000km). The first 1,200 miles (2,000km) not exceeding 4500 rpm or full-throttle starts among other things. From 1,200 miles to 2,000 miles, increasing road speeds gradually and engine rpm's in excess of 5,000rpm for brief periods.

On proper break-in, there are two mainstream schools of thought: (1) Drive it like you stole it, aka "run it hard"; and, (2) Follow the manufact's instructions, aka "go easy" for the first few thousand miles.

The first method of break-in, "Revving the daylights out of the engine from the start" is certainly controversial. But, there is the belief out there among many that optimum ring seal (read: Maximizing an engine's HP/Torque) is achieved by many short bursts of hard accel/decel. See here for one synopsis on the theory: Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

For me, I use the second method, following the manufact's instructions. But, I do make it a point to vary the engine speeds as much as possible by using the Sport Mode/paddles as much as I can, especially in traffic.

However one breaks-in their motor, most every (if not all) manufact tests their engines in some way before we ever get our hands on them. Having a "pure" motor without ANY runtime doesn't seem to happen much (unlike the situation where one builds their own motor and runs it for the first time).

To address your last point, I don't think "Dynamic Mode" hurts break-in per se--if you don't use it to its full capability until past the 2,000 miles mark. (But, it's tempting, isn't it?)

 

The original manual had no mention of break-in, so I violated it quite a bit by the time we tracked the info down from Jaguar. Dealer had no idea. They added it to the 2nd addition of the manual. Sounds like you have a 3rd edition.

 

Given the fact that car now have "black Boxes" that can store lots of parameters, it might be prudent to follow the makers advice just in case there's a warranty problem down the line. "Big Brother" is becoming much more a part of our lives.

 

Thanks for all your input. I've certainly decided to follow the manual as much as possible. Although I have to say, there's nothing more satisfying than the fluttering sound when you take your foot off the gas!

 

Great point.
