Hi. I watched some of your YouTube clips and they are genius. I have a 2018 Nissan rouge I purchased from my father at 23,000k. I changed oil and filter every 5k (Mobil 1 ow-20 and fram ultra filter). Can I push it back every 6k? Also, approaching 42,000k I haven’t done any tune up other than changing in cabin and engine air filters. What should I be looking for in a tune up at the mechanics shop? How much should it cost? Lastly, is sea foam good in tank/crankcase. If so , how often should I be running it in both applications? Thanks!! -ed
Can I push it back every 6k?
If majority of your commute is on the highway at constant cruising speed, sure.
What should I be looking for in a tune up at the mechanics shop?
Check your owner’s manual for the maintenance items at your mileage. Your vehicle is probably due for a transmission fluid change and brake fluid flush.
How much should it cost?
Price around various independent shops in your area.
is sea foam good in tank/crankcase.
Don’t bother. Scotty has made numerous videos showing why not to use sea foam in cars.
All the best!
