2000 Seville STS

Whoa, that ring thing sound llike you have to get the engine rebuilt. I read one review where a guys said he goes through a qt every 2k or 3k miles. I guess that would suck for a fairly new caddy.

I also found some review where people said you have to get special tires for these cars or you will get a vibration at high speeds. What's up with that? i have a new set of Yokohama Avid H4s that I planned to move from my Buick Lesabre to the new car. Will these tires work ok?

Well, not "rebuilt". We just go in and replace the rings. And if you
go thru a quart every 2-3K miles....that is excellent oil usage for
this engine. There are a couple of mistake that people make when
driving these cars, one....they don't drive them hard enough...it's a
300 hp engine that needs to be driven like you stole it. Two.....the
oil level needs to be checked "hot" and after sitting for 2-3 minutes.
This engine has about 8 quarts of oil in total sitting in the engine, there
is a lot of expansion of the oil between cold and hot and if you overfill
the engine even a bit, it burns it off quickly. So.....people often check
it when cold, fill it to the top of the hash marks and then it burns off
the excess and they believe that they are using oil. It's better to check
the oil level as I described and even then, just keep the level halfway
in the hash marks on the dipstick.

We do have vibration issues with this car. We have a special tire balancing
machine that measures "road force" not just static and dynamic balance of
the tire. Road force means how many lbs of force the tire exerts on the
road at any given point around the circumference of the tire. You would not
believe how much road force a perfectly good looking tire, that balances
up well, will exert. This give you the vibration. GM's fix for this is to
selectively "grind" off parts of the tread at the high "road force" area of
the tire. That's if it's really bad.....usually you can get the road force
within
specs by rotating the tire on the rim.

Personally, from what I've seen on the balance machine....Michelin tires
are the best.

I had just put a brand new set of Michelin's on my wifes 98 Aurora, two months before she totaled it. This was back in Feb. or Mar.. I argued with the insurance company but they wouldn't budge, either I bought the entire car back or I could only get my personals... These Yokohama's I just bought for my buick are SUPPOSE to be comprable to the Michelin except quiter. BIG difference from those American Generals. I've had the buick up over 100mph and no vibration but it also doesn't hug the road very well. I think the struts are bad but it only has 34K miles. The car is hard on bumps, no plush feel like a Buick Lesabre should have.

I'm not going to get the caddy, my wife reminded me that it cost to be a caddy owner. I drove the car most of Saturday and what a dream of a car it was. Mesagging seats, power under the hood and a ride like I wished my Buick had. What a great car!
