Recommended full Synthetic oil for LS1 162,000KM???

[FATMOE]

You will be fine with 10w60 Castrol edge. I've been using it for 3 years now with no problems.

Occasionally it's noisy on cold start up, but that's pretty normal with the ls engines.

I know this has more then likely been covered a billion times in the past.

However I just got my VZ and the oil is black,

Thanks

Just what colour do you think old oil will be, I run full synthetic 10w40 and change oil and filter evry 5k and oil is always black when I change it.
With an engine with those K's you'd do well using an oil with a hot viscosity of 40 or higher as any lower maybe too thin and give you too much blow by.

obviously I know its going to be black, but not tar like black.

Penrite 15w-40 or 10w-40 FTW why are people running a 60 grade oil???

On the LS1 forums, the guy who runs (or owns, cant remember) mainlube recommends castrol edge 10w60 as the best off the shelf oil (best protection and properties). If you're really nuts, go with mainlube, but its $40 a L, so works out quite expensive.

Apparently with these sorts of oils, changing the filter more often and sending oil for analysis means you can extend the service intervals quite a lot as synthetic doesnt degrade quickly like mineral. I'm pretty sure he said many people using synthetics over change their oil (i.e. they change it too much) because they are used to those sorts of schedules thanks to years of mineral oil use.

Because we can.

Tar like is a differnt matter altogether.
Either the previous owner has used a really low grade oil of he never changed the oil or only once now and then.

Did you read my post?

I am going to buy and change it this weekend, I am either going with the Castrol 10-60 or Pentrite 10 or 15-40, I wont be doing a lot of hard driving if any.

go the pentrite i just think its a better class of oil then the castrol
