I have a 2019 Kia Sorento with the 3.3 V6 engine. Just got it in December and have 3000 miles on it. I have only used top tier fuel since taking possession with 50 miles on odo. Pretty sure the dealer didn't do that when they filled. So with me always using TT fuel, and if I continue to only use TT fuel, would it be necessary to use an additive at some point. I'm partial to Techron. But will it be necessary if always using TT?
Thanks.
Thanks.
