Synthetic oil change

I'm considering switching my 1995 GMC Suburban 454 cu.in. motor with 150,000 miles to a synthetic oil.  Anyone see any problems with that?

  1. The oil will work fine as far as the engine is concerned, The problem would be that synthetic oil will get thru any leaks. If you already have leaking valve covers or pan gaskets or any engine gasket it could increase your leakage.

  2. Correct. Valve cover gaskets were replaced last year. I also read that there might be some oil leakage but it will reseal after a while - dunno.

  3. I don't see any problems but what is your reason for switching. hasn't your old oil done the job all this time? Unless you are just doing this to make yourself feel better about taking care of your car, I wouldn't spend the extra money myself, but that is just my opinion. A lot of people swear by it.

  4. I think the main reason is an ad in our local paper advertising a Lube, Oil & Filter Service with brake inspection and 59 point inspection for $24.95. They are a big tire and auto service dealer with four locations in our area. The oil is Kendall Synthetic Blend. Oh yeah, on top of the $24.95 is a hazardous fee, tax and disposal rate. California taxes the hekkies out of us. Next to come is the ban on plastic bags and a 25¢ charge for paper bags at our grocery stores.



    I guess the next question is - any comments about Kendall?

  5. Definitely no problem with switching over to synthetic oil. No real need to as long as you change you oil regularly. As for Kendall oil, and for most all oil sold, they all have to meet SAE standards. This keeps them all at a similar quality.
