Yes, GEICO offers eligible active-duty, retired, National Guard, and Reserve members up to 15% off certain car insurance coverages. GEICO does give a military discount, and the current official wording is pretty clear: eligible service members and veterans may get up to 15% off certain car insurance coverages.

Yes, many 2001-and-newer cars can run E15, while older vehicles, motorcycles, boats, and small engines should stay with E10 or less. E15 is one of those fuel labels that can stop you mid-fill-up.

Yes, 4H can be used at highway speed on slick or loose roads, but dry pavement can strain the drivetrain and hurt handling. 4H sounds simple: twist the knob, get more traction, keep going. The catch is that “can” and “should” are not the same thing. A lot of drivers hear that 4H is fine

Yes, Jiffy Lube offers wheel balancing at many locations, though the exact service mix and price can vary from one shop to another. If your car starts to shimmy on the highway, the steering wheel buzzes, or the tread looks uneven, tire balance is one of the first things to check. That’s where Jiffy Lube

Yes, a late transmission service can stir up worn material, trigger slipping, or expose damage that old fluid was masking. Changing transmission fluid is usually good maintenance.
