Just bought my Navi and my grandpa condition is as kiddos to ONLY put premium in the tank of his Lincoln.
That said, I get the logic. You just paid a lot of $$$ on a car, give her the best tools to reach peak performance.
Only 1 previous owner and she only used 87 octane.
Can I switch to premium now with issue?
Thanks
Hi UnfortunateLuck611 and welcome to the Lincoln Forums.
“driller”, “kep5niner” and the Owners Manual photo sum it up perfectly.
And yes, if you wish to, you can switch to premium fuel now, despite the fact the previous owner used 87 octane.
Just some added information:
- Our engines are designed to run on minimum 87 octane, and will run on 87 octane just fine with no worries about engine damage.
- However, they will provide peak advertised power using 93 octane.
- The loss of peak power with 87 octane will be in the 5-10% range.
- We only obtain “peak” power during near/full throttle driving, so most drivers rarely utilize peak power in their daily driving.
- If towing or in hot weather, severe duty driving etc., premium fuel (91-93 octane) will provide better performance and more protection against engine knock. So using premium in those scenarios can be a good idea.
- If your stoplight racing days are still happening, use premium,
More important than the 87 versus 91/93 debate, is fuel quality. So follow the Owners Manual guideline and only use “Top Tier” rated fuel from Top Tier certified stations. And avoid discount/convenience store fuel.
Let us know how you make out and good luck.
