Viscosity took very little hit as it starts around 8.0. And since you're not really burning any oil, your cats are probably fine with the slightly elevated phosphorus vs. the 800 ppm's in GF5 oils (if you have cats).
Any engine mods and what are the driving conditions? Is this the newest Ester Core 300V?

The only engine mods that were in effect during the oil use was an AFE drop-in dryflow filter. This is my daily driver. I accelerate quickly ... a lot. Well, as quickly as this car can go anyway. I have not yet autocrossed it. But that's mainly due to lack of time.
I installed the TRD Intake a couple weeks after doing this recent oil change. All cats are still present. I meant to change the oil at 5K, but lost track of time and mileage and it slipped to 6K. But, based on the numbers, I could likely go longer.
I got the 300V a few months back from my distributor. And the price leads me to believe it's the newer formula. The cans look about the same though and I don't think I have any old cans from the previous oil to compare details.
Since I put about 8K miles/year on the car, it will be a while before I do another change. I'll be sure to post the results on this thread to keep a good running history.
