Q: Will this work in harley davidson primary and clutches

11 months ago
1 Answer
  • A: No, Ultra1Plus SAE 75W-90 Synthetic Limited Slip Gear Oil API GL-5 is generally not recommended for use in Harley-Davidson primary and clutch assemblies. The correct fluid for a Harley-Davidson primary and clutch must be compatible with wet clutches to prevent slippage. Tractor Supply Co. carries a suitable Ultra1Plus SAE 20W-50 Synthetic 4-Cycle Engine Oil that can be used in all three holes (engine, primary, and transmission) of many Harleys.

Q: can this be used in a transfer case in a 2010 4wd toyota tundra? or do you make another 75w90 product for transfer cases.

a year ago
1 Answer
  • A: Hello, thank you for your question. The 2010 Toyota Tundra transfer case usually requires a 75W-90 gear oil with an API GL-4 rating or a Toyota-approved transfer case fluid. This Ultra1Plus GL-5 oil is better suited for differentials, not transfer cases, because GL-5 oils may be too harsh for transfer case components.

Q: 2015 F150 differential, will this work in it

a year ago
1 Answer
  • A: Hello, thank you for your question. The Ultra1Plus SAE 75W-90 Synthetic Limited Slip Gear Oil meets the API GL-5 specification and is formulated for use in many limited-slip differentials. However, we always recommend checking your vehicle’s owner’s manual or consulting with your dealership or a certified mechanic to confirm the correct viscosity and specification for your specific model and driving conditions.
