Re: What grade fuel do you use?????
It doesn't matter...if the engine doesn't care.
An extra $3.50 per tank can translate to as much as $200 per year in fuel.(at a tank per week fillup)
How many tanks per year do yu average??? That's a personal call.
i.e., if your FJ is a weekend leisure vehicle then Premium won't dent your wallet.
Keep things in perspective. If it runs fine then it's ok to use Regular.
Premium generally yields somewhat better performance. Some notice it...some don't. But these Toyota engines control engine knock/ping by adjusting timing accordingly.
The higher the Compression ratio the more Octane yu would want ...as a general rule.
