There have been a few oils over the years that seemed to grab a huge amount of attention when they came out. The original Mobil 1 full synthetic comes to mind. I know when I was in high school auto shop in the early 80s that was talked about like it was some sort of unicorn magical elixir that we could only hope to afford to put in our cars one day. A few years ago Pennzoil Ultra Platinum seemed to grab the headlines, and has been my oil of choice for a while now. Now the past 18 months or so, Valvoline Restore and Protect has seemingly taken the oil market by storm. And by the thousands of positive reviews you can find online (many right here on BITOG), rightly so. So after doing a lot of research and reading, to include this forum, I decided to take the plunge and did the Valvoline Restore and Protect oil change today on my 2015 Hyundai Sonata 2.4l. Working on the 2nd engine, first went out at 122,800 miles in August of 2022. The "new" engine now has about 50,000 miles on it, running nothing but Pennzoil Ultra Platinum 5W20. Upped that today with the Valvoline Restore and Protect to 5w30, again after a lot of research pointing me in that direction. Now my replacement engine has not shown any oil burning / loss up to this point, so it's been doing well, and also doing oil change interval between 3-4,000 miles. I was just a little over 3,000 miles today before the change. Also using a Purolator One filter. I had been running the Boss on my Sonata and in my 1996 Ford Ranger as well, but after seeing some information that seemed to point towards those filters possibly only filtering somewhere around 45 microns or larger, I decided to drop "down" to the One, which is a little cheaper, but, has a higher efficiency rating. I might be what many would call old now, but you can teach me a few new tricks.
