I used 87 for my first year of driving. It was okay I thought. Now I run 89 and the car feels A LOT better. I also tried 91, but the only thing I noticed was a slight decrease in mileage (heavy foot maybe...). I've read opposing views on the question - Does higher octane mean lower fuel consumption?...

Erm...guys, that 850R in Raleigh wouldn't happen to be black, would it? Is it at a dealership and what's the price? The things - I went to see a black 850R in Raleigh a while ago at a dealer and it was an absolute dog!!! Needed bodywork, it was leaking PS fluid, front suspension was bust, all the li...

Thanks for the informed response! The ticking that you mentioned. I've heard it, but it only ticks 2-3 times, and that could be the exhaust manifold as you mentioned. My car is a NonTurbo, and it's been driven very carefully. My clogged PCV doesn't like high revs :) I guess I'll stick with the PEAK ...

So what CAN happen if you don't use Volvo coolant, or mix coolants? The reason I'm asking is because a few months ago, I was running a bit low on coolant. I took a look - the color was green. So I went and bought a bottle of the 50/50 PEAK green coolant. I haven't noticed any overheating issues. But...

mercharch, thanks a lot for the pictures! I'm changing my speakers too and I was wondering about the pos/neg wires

You can have a leaking RMS and no problems with the PCV. That's what I'm (was) having. No smoke from the dipstick, no oil coming out of the cap...yet terrible leak from the RMS, which soaks the underside of the transmission. I was losing a quart every 500 miles. Since then, I've improved the situati...

Ahhh...the good old RMS. I've been fighting mine since the summer. I switched to Mobil 1 High Mileage (I don't know what it had before) and it made it worse. Put a bottle of Bar's RMS Stop leak...nothing changed. I was losing as much as 1qt per 500 miles :shock: :shock: :shock: Then I started to put...

Horrible? How horrible? Is it really loud? The sway bar links are not generally loud...they just click. Does it sound like something is loose (like a clunk)? or is it a much harsher sound? You should check your control arm - lift the car (on jack stands), lock the steering wheel, put your hands on 3...

It depends a lot on your area...here in the Appalachian mountains I get about the same as yours - 23/24mpg.
When I east to VA I get as much as 30/31mpg, because of the flat surface.

I'd be interested to read which ones fit the 850 too. I'm looking for a cheap set as well (not necessarily OEM).
