Recommended: fuel/gas octane (87) & engine oil grade (0W-20) -- 2025 4Runner 6th Gen

[Administrator]

From the 2024 4Runner 6th Gen Owner's Manual:

Gas/Fuel Octane rating: 87 Octane (Research Octane Number 91) or higher

Engine Oil Grade: 0W-20

Outside temperature:​

SAE 0W-20 is the best choice​

for good fuel economy and good​

starting in cold weather.​

If SAE 0W-20 is not available,​

SAE 5W-20 oil may be used.​

However, it must be replaced​

with SAE 0W-20 at the next oil​

change.​

Fuel / Gas Tank Capacity: 19.0 gal.

Thanks for the confirmation on recommended fuel octane rating.

Something to consider for anyone thinking what could be gained from running premium fuel (91+ octane):

Premium fuel 91 octane gains 20 hp / 14 lb-ft torque (vs. 87 octane) on gas engine 2.4L i-Force -- dyno test

if you are saying you have to put 91 octane gas in the new 4 runner, In NC your choice is 87,89 or 93, there is no 91 and the difference is about 75 Cents a gallon, so a fill up will cost you about 15 dollars more, I have a 2007 BMW 335i that takes 93 octane gas, dont drive it much anyway but filling up is painful I was seriously conserdeing a new 4 runner but I doubt I will be buying a new 4 runner, the Lexus GX models I dont like because the back hatch opens up like a door at lease on older models. I have a 2014 4runner with 225,000 miles, I might just buy a used 2020-24 model from carmax with less miles or drive this one till it totally craps out.
