Did my 1200 mile oil change today

[KyleWI]

FWIW, I changed the Engine oil 4 times, diff 3 times, manual trans 3 times. Blackstone keeps telling me to go further (I'm basing it off the number of track weekends) for every single one of the above.

Engine oil will now target 4 weekends, diff 8 weekends, and trans 8 weekends. I'll just keep doubling it until Blackstone tells me otherwise.

Additional info for y'all, the diff fluid AND manual trans fluid came out clear during the 3rd change. I'd highly recommend getting rid of the factory junk. I really don't see why Nissan "Requires" their formulation for the trans, but I've yet to have a problem with some motul 75w90 in the trans.

I know you're basing it off of track days, but do you know approx how many miles you're going between changes. Also, how many sessions per track day? Assuming the standard 2 / 2.5 hours (4-5 sessions).

I've switched over to RL MT-85 & 75W-90 GL5 for my application, but haven't changed and have ran 4 track days on this new fluid.

So mostly curious of your results.

Each weekend is 2 days, about 4-5 30 minute sessions, so a total of 4-5 hours of time on track per weekend. I changed the diff/MT at the same time, around 7000 miles of wear. Engine probably had 5000 miles of wear on the last oil change I did, so it was about due anyways (Unfortunately only had 2 track weekends on that set of oil).

The conclusion I cam to was based off the last change which is the above data ^^

Incorrect. Nissan says every 10k miles. I suppose you are smarter than a Nissan engineer?

I doubt any of us has talked with a Nissan engineer but with fifty plus years listening to engine builders from local racing classes to Indy I can assure you changing your oil at the first 1500 miles is good advice.....

I just go by the habit of changing engine oil after two track days/weekends, including the few miles in between (not daily), on any track setup car, Z or otherwise, turbo engines especially! Cheap insurance $$ well spent on best oils. Tranny a bit longer intervals but diff about every 4 cycles.
