Subject: Re: Does anyone use synthetic oils?

I too use synthetics. I have a '80 900T hatchback with 125k miles and no engine problems for my dailey driver. The original turbo is just fine. The car had been on regular oil for 15 years and 80k highway miles when I bought it. Started it on synthetic blend oil for 2 changes and then went to full synthetic. I use Mobil 1 or Pennzoil. I wasn't aware that this had an effect on my 5-speed transmission, but it works fine. It's not as smooth as my mom's 9000. Would thicker oil smooth out the shifting? Do you think I should use 0w-30 or 10w-40 or 5w-50? thanks, On 05 Aug 2001 16:40:02 GMT, dsjkallennopsamcom (DSJKALLEN) wrote: >I have used Mobil 1 in my vehicles for some time.
