'08 WRX Turbo
Short throw shifter
I'm just over 2000 miles and thinking about my first and future oil changes. This is my first Subi and I don't know a lot about them. I've always used Valvoline 10W-30 or 10W-40 in all my cars (mostly Fords) and have been lucky to have no major engine issues in the 10 or so cars I've owned and maintained in my life. I used to always do my own oil changes but in the last two years I've come to use a Valvoline oil change place down the street from my work because they are actually a little less now than if I buy all the stuff myself with today's oil prices. Plus I don't have to break my back under the car. So my question is: Can I still use Valvoline 5W or 10W in my WRX and be good? Or should I rethink oil and go with something better?
This is a new technology car for me.
The other thing is an odd clutch issue where at certain time the clutch won't slip when I release the pedal. It does nothing and then suddenly drops to full engage as if I dumped the clutch. I've never witnessed anything like it in any other car I've owned! It's been the most repeatable when I stop at the mailbox on a hill. I go up in 1st, stop, get mail, then let up the brake and roll backwards to line up with the driveway. When I release the clutch it has no resistance and then finally dumps... usually stalling.
I've noticed this now at a few stop lights too, I know where it should engage but it just doesn't, I let it out way past that and it finally lets go, sometimes stalling if I don't watch it and keep the revs up. I don't get it. It's very intermittent though, there are days that it drives fine and I haven't noticed any difference in conditions such as weather when it acts up. Sometimes, if I'm paying attention, I notice that it will not slip, so I push it back in, rev up some more, let it out and eventually it will slip and I can lower the revs and let it out normally. I know it's a hydrolic actuated clutch, but could there be something wrong or interfering with my action on the clutch pedal? Do you think the dealer should check into this one?
I started thinking that I'm just too fast for it so I slowed down my go-from-a-stop reaction times and it seems to be more responsive without the clutch drop-out problem. But cmon, this is supposed to be a sports car right?
Any tips much appriciated, sorry for being long winded.
