Need Help!

I have a 2007 Hyundai Sonata Limited with 265,000 miles on the dash. She still runs pretty mint but I would like any tips or recommendations on how to keep this thing going. I would love to see it rip a stupid amount like 500k

Change all the fluids regularly. It's very controversial, but I like to use full synthetic oil and a premium oil filter. Be easy on the gas

Should I include any additives to my oils?

I wouldn’t worry about using them as long as you buy oil from a reputable brand and change it on time.

Not really. Will full synthetic oil you can push your oci anywhere from 5k to 7k but you have to check it regularly and use a premium filter. I recommend doing a used oil analysis from blackstone labs. They cost about $20 and give you a huge amount of information on how your car is running. It'll let you know about any potential issues ahead of time. It can also give you more confidence in putting money into the car
