Finally! Took advantage of a 59F winter day to do some oil changes in the household. First the 2012 Dodge Grand Caravan which just hit 3,500 miles since the last oil change in August and the Mobil 1 synthetic I put into it looked awfully black. Happy I didn’t wait longer to say 5,000 miles because it would have been unnecessarily dark. The van is only used for short trips and the start/stop engine wear probably contributed to the condition of the oil (as opposed to say higher highway mileage). The Miata too got an oil change earlier than what I planned. It was about 724 miles short of the 5,000 mile interval I have determined to be ideal for my Mazda. Like the van the oil was dark. I used Pennzoil Platinum 0W20 on the last oil change so I’m going to speculate that my car doesn’t like this oil. It doesn’t burn it as in oil disappearing between oil changes, I never had to top off oil. But it certainly burns to change color from brown to very dark brown. It wasn’t all that black, but it was terribly dark.
Anyway, I’m excited about this oil change because finally I am using Castrol EDGE synthetic motor oil. I mentioned this oil several years ago when I first tried Mobil 1 and prior the time I started using Pennzoil Platinum in order to make an apples to apples comparison between the top readily available oils for my Miata. Sure there are other oils out there that some may consider “better” like Red Line or Royal Purple, but the premium trio: Mobil 1 / Pennzoil Platinum / Castrol EDGE are the most readily available and affordable options on the market here in New Jersey. So finally… Castrol EDGE is in!
My opinion about this oil will realistically be made about 5,000 miles from now when it’s time to replace the oil I just put in, but first impressions are good. There’s no difference in engine sound or feel since changing from Pennzoil Platinum to Castrol EDGE, so I’d say so far so good.
Here’s some pix:
It’s worth noting that I followed Chris’s advice and only hand tightened the K&N HP-1002 filter. Unlike in the past when I turned the 1 inch wrench to tighten it and noticed oil seepage on the top of the filter where it bolts up to the engine, there was none of that this time where Chris did the last oil change for me. So I looked at the way the filter say after he did it, and tried to match the same with my oil change. Looking up at the filter you see just the white side, none of the K&N stickers are visible. That seems to work best. It’s nice and tight by hand-tightening, and that seems to work well.
I also took the time to adjust my front license plate Cravenspeed mount. Lately after driving on the highway it seems the wind was moving the plate out of position (it was askew) so I lowered it about half an inch down to also match the way Chris has it on his car. I think it does look great. Hopefully it sits in place as it should.
