I use Costco synthetic oil and change it every 5K

Used the same change intervals with Mobile One synthetic before switching to Costco oil. It's just cheap insurance, and I don't mind changing the oil while it's still in great shape.

Since it is car maintenance day...who has used 20,000 mile oil? -- Coach McGuirk 04/12/2022 5:55PM

My car monitors the oil and calculates the life left -- Tafkam Hokie 04/13/2022 10:15AM

I dunno know what mine is. I just cop it from the recycle area @ the dump ** -- Riverguy 04/12/2022 7:04PM

I'm no dummy. I haven't fallen for that "you need to change your oil" trick -- HokieGator 04/12/2022 6:51PM

Well, if you do, diligently check the oil level. I have a hard time -- UEMcGill 04/12/2022 6:27PM

You can always do oil changes between their 10k intervals. -- EDGEMAN 04/12/2022 11:07PM

Costco and Super Tech are both excellent motor oils. -- YardBird 04/12/2022 8:13PM

Pretty sure those two are almost the same exact blend -- EDGEMAN 04/12/2022 8:20PM

I use the Mobile 1, makes a world difference in the sound of the engine. ** -- AZHokie59 04/12/2022 6:36PM

Youtube mechanic Scotty Kilmer doesn't trust 20K mile oil.Oil is not that -- HokieDan95 04/12/2022 6:24PM

I use full synthetic...usually go between 8 to 10K, probably would -- Tuckahokie 04/12/2022 6:03PM
