is 5000 miles too long to wait for an oil change?

To the OP:


I'm brutal on my engine. Cold-starts, short trips, etc.

Even so, all my Blackstone Oil Analysis reports come back with stellar results, and lots of oil life left. Blackstone is always trying to encourage me to go 6K miles on conventional Shell 5w-30, however I don't (yet), due to the warranty...

Motomaster Formula 1 conventional. Basically, a Shell conventional oil, privately-branded, with a slightly lesser additive-pack.


Next OCI will be actual Shell-branded 5w30.

o.k. . We're using SHELL 5w-30 conventional for now . Get it for $2.20 a quart . Dumped the SHELL 5w-30 synthetic for both to see if the leak stops for both with conventional . May go to a run of VALVOLINE 5w-30 dino . That's apparently a little thicker . Checked the 2010 earlier for the leak after being driven for over a 100 miles in 2 days and there was no oil . When drove the 2008 for 100+ miles in 1 day it was wet to the touch . Recleaned both . Will keep monitoring the two . Thanks .
