Have an 2019 Encore and was told by everyone that i need to use 89 Octane since this car has a turbo. Is that correct or have ive been wasting money?
That makes no sense whatsoever. Gasoline does not flow through the turbo only air on the intake side and exhaust in the output side and again your owners manual clearly states you can use 87. The engine is also equipped with a knock sensor which will adjust engine parameters based upon the octane used.Was told using 87 would ruin the turbo?
You are wasting your money. It was designed to run on 87.
It can't hurt but I personally go by the owners manual. No auto manufacture wants warranty claims.Was told using 87 would ruin the turbo?
I just spent 1500.00 in repairs on my 2015 encore. Blew the Valve Cover and Intake Manifold due to carbon build up on the PCV valve. Our gas has 10% ethanol so I’m blaming bad gas. I have 160000 Km and mostly highway mileage.Have an 2019 Encore and was told by everyone that i need to use 89 Octane since this car has a turbo. Is that correct or have ive been wasting money?
I read the following short article on the subject of turbos and octane in Popular Mechanics:Have an 2019 Encore and was told by everyone that i need to use 89 Octane since this car has a turbo. Is that correct or have ive been wasting money?
Actually, there is some evidence that using lower octane, especially in warm climates like Texas and Florida is causing premature turbo failures through cracks or other damage. That is correct that the knock sensor will pick up knock with lower octane fuels and retard the ignition timing. What happens with retarded ignition timing is that it can drastically increase exhaust temperatures. These increased temperatures can cause accelerated or increased stresses on the turbo. The potential for damage is more likely for people who have a heavy foot or live in hilly areas. This is compounded in warm climates as the IAT is increased further under boost.That

It isn't the heat, the ECM will compensate for that, it's 99% humidity that's the problem, try as you may you cannot combust water. Octane just makes gasoline less volatile so it ignites when the spark arrives, It doesn't make it a better gasoline since it has less energy and for all the people that say they have better gas mileage with 93 I would like to see factual proof.I live in GA and it gets really warm during the summer here. I have noticed a drastic loss of performance running 87 octane. I think in warm climates or "spirited" driving, that a minimum of 89 octane should be used. I work for a major car manufacturer (not GM) and noticed that on all the vehicles we test that running regular in a non-turbo with 87 recommended fuel, that there is some knock retard with regular driving.
