You're right - no maintenance at all is ever really "needed," depending on how long you want the vehicle to last.

By the same token, I could never exercise and eat fast food all the time. A good diet and exercise are not "needed." It's really just a question of how long I want to live.

The issue is do you "want" it, and to answer the OP's question: Yes, they are a good idea.

Might want to read the complete response and keep irrelevant comments out of the forum.

Maintenance as described and done in intervals suggested in the manual is maintenance.

There's good maintenance, bad maintenance, better maintenance, minimal maintenance, yada, yada.

Which do you prefer?

Might want to try and answer the OP's question instead of trying to be a dick.

Wow, Nadirpoint. My comment was to support your comment about GM saving on manufacturing costs. And you want to call other people dicks?? Look in the mirror if youre looking to find the true dick on this thread

Sorry if I misunderstood what you said. Obviously I did, because I did not get your point or your meaning, and took it the wrong way.

Yeah, news flash: I can be a real dick sometimes. Just ask my wife!

Lol. Misunderstanding is very common and we are all guilty of it. No problem man
