Thank you very much, I have a Haynes and it was saying to run straight 30 weight... Sounds wrong to me...

The engine is supposed to be rebuilt, but maybe 20,000 ago... So I have been running 10 30 Castrol, as I think Castrol is the best.


I also had another question.

Where would be a good location to place a after market water temp sensor? My stocker acts funny and is not accurate.

I see some sensors under the neck, but I am not sure if I can disconnect them.
