  1. Why take a chance on a harsh solvent which could harm some sensors or seals somewhere in the engine bay? What I do not like about modern cars over those I owned in the 1960's is there are too many sensors to feed the computer. I would just use a pressurized air hose.
  2. Per owners manual, it all depends on severity of use..such as hilly roads or stop and go describes your 45,000 miles, then change the CVT fluid.
  3. My new car dealer gave me some coupons to buy GM accessories, and it saved me $100 with the coupon. Got 4 custom fitted rubber mats, very useful since I live close to the beach.
  4. Sure, if it is all slightly downhill with a little bit of tail wind
  5. I calculated MPG by keeping track of actual miles driven between fill-ups and exact amount of gas used. The number was slightly below 34. But the computer average shows slightly above 35. Which can only mean the computer numbers are slightly inflated, at least on my Spark 2017 with CVT. Note - my driving is similar to distant suburb model.
  6. Agree totally on how good 2017 spark is for the price. I am driving 2017 LS with CVT and like the tranny without having-to shift gears. our other car is a Chevy HHR and it rides much more stable at speeds over 60mph. but not as much fun to drive in urban areas.
  7. Ouch...mysterious shorts in the electrical harness are heavy on man-hours.
  8. There are a lot of steps for the technician to follow. These techs are known to make mistakes. If your Spark keeps giving you lower MPG (4-5 less is horribly bad) I would take it back to the dealer and complain vociferously.
  9. Service Procedure Note: Carefully read and follow the instructions below. Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. When required install the EL-49642 SPS Programming Support Tool to maintain system voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger. Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including daytime running lights), HVAC, radio, etc. Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO. If the Same Calibration/Software Warning is noted on the SPS Controller screen, do NOT attempt to program the module. No further action is required. Refer to the Warranty section of the bulletin and use labor operation code 9102966, Module Programming Not Required. Important: Before beginning the programming event, be sure the computer is connected to the MDI/MDI2 through a USB cable. DO NOT DOWNLOAD the files wirelessly or via Bluetooth connection. Reprogram the Transmission Control Module (TCM). Refer to Transmission Control Module Programming and Setup MR8 in SI. The Transmission Fast Learn procedure is REQUIRED with this programming. If there is a pop-up in SPS indicating otherwise, ignore it and proceed with the Transmission Fast Learn as SI recommends. Record SPS Warranty Claim Code on job card for warranty transaction submission.

  11. LOL when we lived near Portland, Oregon, it was hilarious to see cars sliding and slipping with 3-4 inches of snowfall. With 6 inch snowfall, the city would shut down for several days! Because they fear salt is bad for environment, so they throw rock pebbles on streets. Guess what, windshield repair business is huge there. I spent 23 years working in city of Chicago driving from Downers Grove to SE corner of Chicago, a 70 miles round trip. I missed may be a total of 4 days of work in 23 years due to snow. 3 of those days were in mid 1960's when Chicago had a record snow fall. Because Chicago salts the heck out on streets. But yes the undercarriage of cars and bodies of cheap cars had mucho rust.
  12. No car is meant to work great for all various conditions. Spark is basically a commuter car for city/suburbia. If you want fast acceleration going from 60 to 100mph, there are plenty of models available. I would not put a corvette engine in a car whose suspension is not designed for it. The other car I drive is a Chevy HHR 2011 with 56k miles. It rides at 80 mph so much more stable than the Spark. Even at 60 mph there is a huge difference in stability and smoothness of ride. But I love driving the Spark in town, because it handles more nimble, and parks in places the HHR would not fit.
  13. Keep full synthetic for recommended mileage interval. Next oil change consider following owners manual, at least until the power train warranty runs out. Who needs to argue with the dealer's service writer?
  14. Unless you are on a very tight budget, I would have it done by someone who does it for a living. This oil change is may be once in the life of car, and it is not worth the effort for a DIY job. Engine oil change is better for DIY projects.
  15. I would use the recommended oil from the owner's manual...a synthetic blend. My guess is the full synthetic might have a slightly different viscosity than the blend. . That may be why you hear the slight groan for a couple of seconds, which is the time difference between the full synthetic versus the blend to reach all moving parts. Anecdotally, I have gotten 150,000 miles without any engine problems using regular 10-30w oil for decades. But it is true synthetic oil can go longer intervals than basic oil.
