Sorry I have been really busy so I didn't get a chance to post this. I did my 5th synthetic change on 9.25.10 at 24,928 miles( heck I just looked at my odometer, it's more than 27xxx now
) Used this oil for about 5650 miles. I know I could have gone to 6-7K but this is the "hot summer used oil" so I wanted to drain it (also it's getting chilly out. Not sure how convenient it would be to do oil change in 30 degree weather
)
As I have mentioned before, I'm going to stick with the Purolator Pureone PL14610 for the future oil changes. I had two filters given to me by K&N. So I wanted to use them first. I switched the filters for last few changes to find any difference and guess what? nothing. The difference is VERY negligible. The ONLY reason I am going with Purolator is because
a. It's slightly bigger.
b. It's about half the price of the K&N. AND
c. All my local auto store has it on their shelf (no shipping/wait time).
I have done oil analysis WITH ALL my oil changes. However, I do not share it on the forum as my driving habit and condition (my cars condition) is different than yours. There's no point in comparing the data. However, if anyone want to just look at it, I can email it to you. Though, keep the copy to yourself. No need to post it on the forum. Also, if anyone just stumbling upon this post, all my oil changes I used Redline 5W 30.
Here are some pics:
BTW, their previous suggestion was 6000-7000 miles. I CAN even go longer now but it's okay. I do two oil changes a year (about 6500 miles each) and it works out perfectly.
If you have any question, please don't hesitate to ask
