The 3.8 Liter V6 powering the Buick Park Avenue Ultra requires only 87 octane fuel. You can use 89 octane but there is zero benefit in doing so. The Supercharged version may require 89 or 91 octane of that I am not sure. Check the owners manual and use exactly what is recommended.
you should never tow in overdrive. that will kill your transmission. tow in regular drive or 3
For a 1993 Buick Roadmaster, the caliper mounting bolts typically require a T50 Torx bit. However, it's always a good idea to double-check, as variations may exist based on specific models or modifications. Make sure to use the appropriate tools to avoid damaging the bolts.

Yes, you can use regular gas in your Buick Century. Most models are designed to run on regular unleaded gasoline, typically with an octane rating of 87. However, always check your owner's manual for specific fuel recommendations, as using higher octane fuel than required won't necessarily improve performance or fuel economy.
Octane has not special application excepting the so-called octane number.
From my understanding, in 94 and newr vehicles, all of them use 134A. 92 & older use R12. 93 Was the wierd year that some has 12 & others 134 A.
87 octane
