Hyundai suggests otherwise.. using premium is a waste since the car is designed and tuned for regular.. it does not take advantage of timing for higher octane fuels.. also adding fuel injector cleaner that often is totally unnecessary.. there’s plenty of detergents already in the fuel.. again.. according to Hyundai.. but what do they know ..
Well I know what works in the Kona well. Detergents depend upon if you're using top tier fuel all the time. If you want to keep your fuel injectors and intake valves clean, then utilize a fuel additive.
Frankly I'm not concerned with what Hyundai says, regarding fuel. Dealers do add a fuel additive every 6000 miles during services, re-labeled (
Chevron Techron) as a matter of fact. They will also recommend a fuel injection cleaning at around 25K.
It is and was a
suggestion and you're welcome to do what ever your little hearts desire. The additional cost per tank full, is nominal.
From my experience with high compression GDI's, premium is always the better option. We ran nothing but premium in our Genesis G80 5.0 @11:5.1 and got exceptional fuel mileage in combined traffic of 26-28 mpg. We are running premium in the N, which is required and the Accent. Both are getting exceptional mileage and are under 200 miles from new. The Accent on winter blend is averaging 37 mpg and is tight as Dicks hatband right now.:wink:
My sons Kia Rio 1.6 Gamma N/A with 26K miles is averaging 34 on regular in comparison. So once again, the above is a suggestion. You can do what you think is right for you. I'll continue to do what works for us.:smile:
Note: I apologize, I did say the Kona has an 11:1 compressions and I stand corrected. I was thinking about our Genesis when I commented. However any 10.0:1 compression ratio is able to run high test fuel, which burn slower than regular grades of fuel. High test burns more efficiently at any compression ratio from 10.0:1 and above. Add a turbocharger which increases combustion temps and it becomes an even more acceptable fuel. This has been common knowledge for decade among hot-rodders, engine builders, racing teams of all kinds, as well as airplane engine manufactures as well. I've commented about this before in other threads. Thanks Mania1 for reminding me.:wink:
