• Coggin Toyota at the Avenues advises routine maintenance reminders and can personalize intervals based on your driving habits and road conditions.
• Keeping regular service records at a certified dealership supports warranty claims and improves vehicle value when selling or trading.

What type of oil does a 1991 Toyota Supra take?

• Our factory-trained technicians use OEM-recommended viscosities and oils to protect valves, bearings, and seals at operating temperatures.
• Choosing the right oil now delivers immediate performance benefits and long-term engine protection, reducing overall ownership costs.
• For exact specifications we verify engine code 6INAG3.0 and confirm the appropriate oil during service at the dealership.

How much oil does a 1991 Toyota Supra need?

• Capacity varies by specific engine and whether the filter is replaced; typical 3.0L inline-6 engines often require roughly 6–7 quarts with filter, but confirm the exact amount in the owner’s manual.
• At the dealership we measure and fill to the precise OEM specification to avoid under- or overfilling, both of which can harm engine components.
• Accurate fill levels provide immediate protection and improved long-term durability; certified service ensures the correct procedure is followed every time.
• If a repair is warranty-covered, it must be performed at a certified dealership to preserve coverage and guarantee OEM parts are used.
