I hate those purists...they're never satisfied!
But, fyi, you don't need to add a stabilizer to get ll-01 oil to last 10K miles, nor do you need a new filter halfway through.
I just did a change at 10K, maybe added a 1/2 qt total during that interval near the end. Filter didn't break, fluid was dark but doing its job and would keep doing it. You don't need anything additional.
Anyway, there are some here that are really tight, and others that are too loose. Best you find a middle ground, but make sure your back is always against a wall so you're aware of Furries if any are around (hide yo dog, btw!).
As desperate as this sounds, in comedy, 'likes' and 'views,' 'friends,' and 'retweets' really help. If I've ever helped you, please help me by friending, liking, viewing, and retweeting. It makes others think I have a following...it'll take you a minute or less. If you could, I'd really appreciate it!
