10,000 mile between oil changes

Straw-man arguments are your specialty, I see. I was extrapolating track usage temperatures to what we see in the 370Z under routine or spirited driving. Again, if you wish to reach temps of 240-260 under spirited driving and 220+ under normal conditions and change your oil every 7500 miles, enjoy! You are obviously misled if you believe this will not cause premature failure.

Ok.. bottom line: you are pushing the limit and ppl who get changes every 2k miles are making sure their 40k investment runs in 10 years... if your wallet can afford changes every 1k miles - you should do it... whats 80 bucks every couple months to have peace of mind? lets please stop this personal opinion rampage that this thread seems to be experiencing

Zguy · 02-10-2010, 02:31 PM

I change mine every 3k or 3 months which ever comes first.... I dont risk it with oil especially since I drive the hell out of my car....

shabarivas · 02-10-2010, 02:36 PM

Seriously - we are nitpicking about an 80$ oil change or less if you do it yourself and people dont think twice before getting a 2k exhaust... priorities these days seem to be out of whack...

Agreed. I'd also consider lazy too as another alternative.

No they aren't. You had nothing of substance nor fact to refute. Anyway, if you'd like to put up some facts I'd like to read them. Extrapolating with track friends doesn't do it here.

And no, I don't track my cars. But I am quite familiar with multi-million dollar naval propulsion systems if that counts toward knowing something about lubrication.

+1 It seems a loss of common sense, as well.

For some, certainly. Others are just misinformed and believe what Castrol bottles have printed on them.

This one?

They describe the heavy use scenario as follows:

Follow Periodic Maintenance Schedule 1 (3750) if the driving habits frequently include one or more of the following driving conditions:
• Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) with outside temperatures remaining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi or door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy, or salt spread roads.
• Towing a trailer, using a camper or a car-top carrier.

I don't do any of those with my Z...?

I'm surprised no one here has mentioned Blackstone Labs to test their oil. From there you should be able to figure out how long to run whatever oil you choose to put in your car.

So you are applying your oil knowledge from multi-million dollar naval propulsion systems to our Zs? How does that work?

No oil cooler??? YIKES! Even my RX-8 had dual oil coolers. now I know what my first after-market addition is going to be.

BTW, how good (accurate, functional) are the gauges in our cars?

The oil temp gauge is good.

schrute · 02-11-2010, 10:58 AM

oil temp gauge is good.

The water temp gauge is hard to read at a glance - just a single lit led in a row of 16 or so. You can add a scanguage if you like keeping track of stuff

I recommend the AE Performance oil cooler. It's a bit more cost-wise, but it actually works as promised and has some excellent key features.

As stated above, the oil temp gauge works well. It's easily read and has enough hashes to be more granular with the temperature readings. The others - all suck. WTF is up with the water temp gauge? That is the most useless POS ever. And I do miss having an oil pressure gauge...temps are nice, but if there is no pressure....ummmmmmmmmmmm.

I really wish we had an oil pressure gauge.
