I added 5 stickers and I gained 15 hp and 10 ft lbs torque :)

 

be very careful...too many stickers can affect the hhr's superior aerodynamics.........

 

At what point does too many stickers void the warranty?

 

Let's look at oil from a different angle.....u don't wear sneakers to kick rocks and you don't wear combat boots to run a marathon.....use a oil that fits the needs of your requirements,and if that means using something other then factory , so be it.

 

I used Mobile 1 since the first oil change on my HHR and PT Cruiser. Is it better than other oils? I have no idea 'cause I never used others.

Twice a year (usually February and October), COSTCO have a $10 off deal for Mobile 1 oils, you can get 6 1-quart bottles at less than $25. That's a pretty price. It was about $20 a few years ago, before the Wall Street trouble hiked up inflation.

 

I've run mobile 1 since day one and I can't say whether or not it has improved MPG but I will say the engine is as strong as ever.

 

Been running M1 since the first oil change. 92K now.

 

Where can you get these stickers from?

 

Summit racing :) or Wal Mart :O

 

Since I started using M1 I have lost weight, I became a champion in full contact origami and I once was able to save a Amazon village from disaster with only a spoon and a glass of water. But I still have yet to meet Elvis.

Summit Racing Stickers are available at Summit Racing. Word is the Stig has one on his personal car!

Oh the Stig uses M1 too.
