Mazda MX-5: Oil Change at 5,000 Miles with Pennzoil Platinum 5W-20 and K&N HP-1002 Filter

I’ve been looking forward to replacing my Mobil 1 synthetic with something different. This season I will be trying Pennzoil Platinum to see how it wears in my Miata. I bought two jugs last time there was a good deal on this product, a 5W-20 weight and a 0W-20 weight that I plan on using for the winter season. The deal came with a K&N HP-1002 oil filter that has a few neat features: 1). the top of the filter is nicely sealed in plastic so no crap finds its way in there while it’s in the box and 2). it has a convenient spot on the bottom for a wrench to slide in and tighten or un-tighten it which makes a world of difference in a tight space where the MX-5 has it’s oil filter.

The oil change has been done at 42,459 miles which is 5,162 miles since the last one and just a week since my 3k mile road trip to Florida. I was not terribly surprised to see how dark the Mobil 1 synthetic got after just 5k miles. They advertise extended range performance of 10k and even up to 15k miles, but I wouldn’t use it much longer than my 5k. I noticed after draining the old oil to return it to Advance Auto Parts for disposal, there were a bunch of tiny metal shavings at the bottom of the pan. That’s not very nice to see. And finally, I must be good at draining all the oil out of the engine because when I refill the car with new oil and crank it up I get a little sound of a knock before the oil spreads through the engine properly. I’ve been following my dad’s advice to false start it a few times for the oil pump to spread the oil, but obviously the few false cranks I did weren’t enough. That had me a little nervous about damaging the engine by hearing that noise which happened for a fraction of a second, but long enough for me to hear it.

Hopefully the next oil change will be around October time at the end of the year so I can put the Pennzoil 0W-20 for winter use and not keep this oil much longer than I’ve had it already.
