Is it better to switch to a full synthetic oil or use the conventional oil? I don’t change my oil, Is it better to have oil changed at dealership or take it somewhere to have changed?
It is NOT a full synthetic oil, however, it IS an excellent oil. I use Pennzoil Ultra Platinum 5-30 which is made from natural gas and not crude oil.I change my own oil and use Mobil 1 (which some people will claim is not full synthetic while others say it is). I would say that if you are changing your oil regularly, either will work well for you. I've read of issues with the oil filter o-ring being aligned incorrectly resulting in a major oil leak. So do you have a local guy you trust? Do you have the "free" oil changes with Hyundai? I've also seen where people trying to use the free oil change service are being required to make an appointment 3-4 weeks out and that's with an overnight drop-off, whereas a local shop is more likely to get you serviced the same day.
I use Pennzoil Ultra Platinum as well. Last year AutoZone had a sale, $2 for the 5 quart jugs. I bought out every AutoZone in a 20 mile radius, I have about 40 of the 5 quart jugs.Pennzoil Ultra Platinum is also a very good oil, just hard to find in stock where I live. Plus some of the reviews I've seen show Mobil 1 may be better in colder weather start-ups. Like I said, it depends where you look as to who says what about Mobil 1 being fully synthetic or not.
