synthetic oil

[freakonaleash1187]

it is time to change my oil again in my z. i have already talked about going to synthetic to the guys over at 300zxclub.com. i was worried about people getting oil leaks when they switch over to synthetic oil, they said it was because with old oil seals, there is dirt that acts as part of the seal and synthetic oil cleans that dirt, which makes it not seal anymore, which causes an oil leak. so my question is, my seals were replaced 15k miles ago, are the seals still new enough to not be affected by synthetic oil? thanks.

i just went and bought Mobil 1 10W-30, so hopefully it doesn't hurt anything, and yeah i have a n/a (look in my sig )

You should be fine. Also, in the summer you may even want to swap 1 or 2 quarts of 15w50 for the 10w30, since synthetic tends to be thinner than conventional dino oil. That is what I do in my TT.

Summer Mobil 1 0w-40 in n/a 15w-50 in TT.Or Redline 5w-40 or 10w-40 ( both exist and are excellent choices)

You'll be fine. I use mobil 1 all the time in my car. And like fred said, I have also used synthetic in cars with more miles and had zero problems. You should be ok.

just as an update, it has been 500 miles since i changed to synthetic, no leaks and she is running great.
