Performance mods that cost nothing to very little that will increase horsepower/torque, gas mileage, reduce carbon footprint, less waste and save time and money.
If you want to monitor your improvements you can get an OBDII diagnostic scan tool with live data feed for $20 and download a free Torq Pro app. You can measure 0-60 mph times, gas mileage, airflow rate, engine temperature, emissions rediness, clear trouble codes etc.. You can monitor after each mod or wait until you done all your mods to see improvements. Here are some things I have done.
1. Check tire pressure. Rolling resistance is reduced with properly inflated tires.
2. Use full synthetic motor oil. Less friction, motor runs cooler, more hp/mpg and longer between oil changes. I use Supertech 0w-20 from Wally world $14.88 for 5 quarts. That’s under $3/qt. Check out the results from the synthetic oil shootout on U tube. It scores higher than the # 1 (Mobil-One) oil. I use the Ultra Synthetic XG7317 longer 20K oil filter. It has twice as much filter media than the XG6607 20k filter which is the recommended filter from the manufacture. I always try use a longer filter if available. You can ask the manufacturer if there is a longer version of the recommended filter. You can send a sample of your oil to an oil analysis lab. You would be surprised how long you can get out of an oil change. Less changes less waste oil and filters in the land fill. While you are changing your oil, go ahead and replace your transfer and differential gear oil with a full synthetic. I use Supertech 75w-90 API GL5. 1 qt. under $7 and good for 100K miles. It has a much higher shear strength and lower rolling resistance especially in cold weather than conventional gear oil. It runs much cooler in the summer, reduces friction, resulting in longer lasting components.
3. Drop in a K&N air filter under $50. Clean every 50K miles. 1-million-mile warranty. Never buy another air filter and no more old filters in the land fill. Increases air flow over regular filter more air flow = better hp/mpg.
4. Check the lowest temperature record where you live. Mix your antifreeze mixture to match that temperature. Premix extended life antifreeze is 50/50. My mix is 45/55 (antifreeze/H20) Which is rated at -17.3 degrees (40% is -6 degrees and 50% is -28.6 degrees). Use bottled drinking water not distilled. My car runs 3 degrees cooler at that ratio. Better hp/mpg. Extended life antifreeze is good for 5 years just adjust with drinking water for your climate.
5. My idle was just a little high. Did an idle relearn and right on now.
COVID-19 time at home. I had to do something. I’m a little stir crazy. Stay safe and I would like to hear what other mods people have done. Thanks
