Thanks, everyone! This was a ton of very good info.
I haven't purchased this car yet, but I'm going to if tomorrow's PPI goes well.
If 5w30 is the recommended oil, would a thin 40 be okay? I've had euro cars up to now, and have almost always used one of four oils: M1TDT 5w40, Rotella T6 5w40, M1 0w40 or Castrol Edge 0w40. I'm leaning
toward either the Castrol or M1 0w40, but I would also like to do whatever I can to help with fuel economy for this gas hungry V8. (Also considering running regular instead of premium gas, but I'm still foggy on if that's okay for this application.)
- Timing belt is due between 90k and 105k miles. You absolutely can DIY it (I did it 2 months ago), just takes some time and need a couple tools to make it work.
How intense of a job is this, and what tools would I need? I got a quote from an independent mechanic that seemed reasonable: ~$1400 for all factory parts and they'd do the "water pump and thermostat and crankshaft seal and tensioner and idler pulley and various o-rings." I'd typically never consider a mechanic for something like that, but I'm time crunched for the next few weeks and I don't have a lot of my tools where I am right now. (I'd probably end up at Harbor Freight.)
I am indeed leaning toward Amsoil for the other stuff, unless I find some unbeatable deal for something comparable somewhere.
