Hey everyone.

I just finished getting my y8 rebuilt, and I was wondering what you guys would recommend for oil. I've read a LOT of stuff about mineral vs synthetic on this and other forums, but there isn't much about what to use after a fresh rebuild.

This was actually the second engine in my car. The first crapped out when I spun rod bearing #4 and cracked the block. I was using regular mineral oil (Quaker State 5W30). I suspect I was running low on oil... I swapped in this newer motor with about 85,000km on it and started running Amsoil 5W30 full synthetic in it. Had that motor for just over a year until I some how managed to spin #4 bearing in that one too, and I just had an oil change the week before.

I shimmed the relief valve in the oil pump with a 0.030" washer to bump up the oil pressure, and the motor is in the car now. I'm running Quaker State 5W30 for the first 1500km, then I'll drain it, and run the next 5000 to 10,000km with the same dino oil for the break in period.

But what about after the break in period? I would like to keep using the synthetic, but do I really need to? I do like to push my motor and get the revs up high occasionally, so I'm wondering which would be best for a rebuilt y8.

Suggestions?

Thanks.

You don't need synthetic, but it's not a bad idea. Research synthetic oils, there is ALOT of information out there about them. Honestly, if you keep up with your maintence on your rebuild, your motor will last. That means change the oil every 5000km or 3 months regardless. I like synthetic for those cold winter months, but really.. it doesnt get that cold here anyways.
