My highway vehicle is a 2001 Hyundai Elantra. Has around 50k miles. It calls for 5w-30.
I was at Walmart and they are selling 5qts of the Supertech 5w-30 conventional for $10! The next price point is Mobil Super 5w-30 conventional which has "5000 mile coverage" on the bottle, for $16.
1. Would I be able to run the Supertech for the same mileage as the Mobil (5000 miles, then change)
2. I have synthetic in my engine now. Any reason to continue to use synthetic?
3. My friend also has an elantra, he is a mechanic (not that it matters, I know) and he said I should use 10w30 instead for better protection from the thicker oil. Is this true?
4. Is it true that Exxon makes the Supertech oil?
Thank you for answering any questions I have
