there are lots of threads and discussion about this already. personally I just use castrol synthenic 10W-30. It comes in a nice 4.4 litter bottle and goes on sale quite often. Tranny I had castrol in it before but I did spend the money after I changed my clutch to use redline and i did notice an improvement. ---

How serious are you about oil? If you’re not serious, run a Dino oil from a reputable manufacturer like Shell, Castrol, Pennzoil, Mobil 1, Quaker State, et el, in the 5w30 weight, and do your regular oil interval changes with a quality filter like the Nissan or NAPA Gold filter. If you actually care a bit, then run a synthetic in the 5w30 weight. If you give a shit, then you should probably run a 0w30 synthetic-I’m currently running German Castrol and it’s great. If you really want to get serious about oil, then you will go to [http://www.bobistheoilguy.com/cms/](http://www.bobistheoilguy.com/cms/) , you will look into oil analysis’, and you will select your weight based on driving conditions and oil pressure. German Castrol is probably the best bang for your buck synthetic oil, for a daily/ weekend warrior car. The reports and oil analysis’ don’t lie, feel free to check them out on that forum. ---

I honestly wouldn’t run 5w30 in the summer, fsm doesn’t recommend it. The oil will thin out especially on a turbo motor where the oil is also soaking up heat from the turbo, of course unless your driving it in the winter but 10w40/10w30 is probably best all round for a generally stock motor in our climate. ---

The oil the FSM recommends hasn’t been availae for purchase in over 10 years. The recommended oil is two generations out of date, as far as oil standards go. I want you to tell me what the first number in the oil rating means, and then tell me what the second number means. I the.n want you to tell me the difference between 0w30, 5w30, and 10w30 at full operating temperature. After you have answered that, I want you to go re-read your post and tell me how you reached the connclusion: that a 5w30 oil will be too thin at operating temperature in our climate, but a 10w30 won’t be too thin. ---
