Screw the metric system and I am a Metrologist (Precision Measurement Specialist)...not a weatherman. I am so old school it annoys me to have to deal with both and I am just "Ugly American" enough to think that our way was the best way!!!

nope you need to reset it...it tells you how on the manual...

I have yet to change the oil in my HHR, the DIC hasn't said too yet and I have 7800 miles on mine. About 95% of my driving is highway driving and when I checked today the oil life read 25%.
Am I wrong and should I have changed the oil or wait till the DIC says so like it states in the owners manual.

I don't trust those things, I would change it. Where will GM be there when you are out of warranty?

SoCalHHR

I most always change my factory oil out at 1,000 miles. That flushes out any metal chips that might have remained in the block from the machining process. Then I slap in Mobil 1 Synthetic - not only does it add protection, it's friction reducing properties actually give a small power increase in the HHR. Several friends who have switched also agree. When you have a 4-cylinder - every little bit counts!

GM has put a ton of research into the DIC, so I'm sure you can abide by it's readings without problems. Most Synthetics can go 7500-miles or further easily, so I'd definitely go the synthetic route. The little extra you'll pay for synthetic will be offset by fewer oil changes.

Hope it helps,

Thanks i finally found it in that manual. I am going to change the oil after 1000 miles like SoCalHHR said and i got a case of Mobil one. I use it in all my cars. I guess the DIC thing will know it is synthetic? or does it go purley off of milage?

Well after doing some research and being a little concerned about the mileage on my HHR and still not having an oil change I found this on GM's website; it answers a lot about the GMOLS (GM oil life system).

How many miles can I expect to go between oil changes when using this system?

The beauty of the GMOLS is that it will automatically adjust the oil change interval based engine characteristics, driving habits and the climate in which the vehicle is operated. For instance, mild highway driving in a warm climate will maximize the interval between oil changes. Depending on the vehicle, this could be in excess of 7000 miles and as high as 12,000 miles. On the other hand, short trip driving in cold a climate may limit the oil change to 3000 miles or less. In general, most people that drive a combination of city and highway find that the GMOLS will indicate an oil change every 5000 to 6000 miles. Additionally, most people maintain consistent driving habits. Therefore, their mileage between oil changes will be consistent. Changes in climate will affect this somewhat.

First oil change done at 3200 miles. I took it to the dealer because I have 3 free oil change, after that I will do them.

I'll be getting my first 3000 mile (actually 3500) freebie oil change after it comes out of the body shop. DIC says 55%. Because I am physically unable to do certain things, I have cut back to what car care I do on my vehicles. I do like to use ramps for my S-10 because it allows more room. Has anyone tried to work on an HHR on a set of ramps?

Changed mine today..
at 960 Mileage....
Mine will get a change every 3000 miles...
standard for me...
