I did a search and I was surprised not to find a thread about this already. I’m currently running castrol syntec 10 30 and a mobile 1 filter. I did a google search and saw that a lot of people are running heavier oils. 10 -40’s or 15 -50s. > **[Recommended Oil for SR20DET?](https://www.driftworks.com/forum/threads/recommended-oil-for-sr20det.61766/)** > > Engine is upgraded.

Amsoil Z-Rod, High Zinc & Phosphorous…10w30 w/ Power Enterprise Filter, currently K&N right now. Shaeffers or Motul are definitely the next oils I’m looking to probably switch to other than what I’m running now. ---

nissan filter, Ams oil 5w30 OE, its very affordable and works great if you change often which I prefer rather than expensive oils that are suppose last longer. ---

> [@Steve660](#): > > Whats your reason for running a thicker oil? Is it a track car or a daily driver? Seeing high oil consumption? A lot of US guys swear on this stuff. It’s a diesel oil so it also has a lot of additives = good. ---

Yeah I noticed that on the US forms guys were running thicker but I figured it was because of the higher ambient temps. I know fsm says at 4 3250rpm oil pressure should be at 57psi. I find my oil pressure starts to drop from that reading once I’m above 180F. Once its up to 200F I cruise at just above 50psi at 3250. I usually turn my fan on the oil cooler at that temp to bring it back down. I was wondering if people run heavier oils to counter the higher temp pressure drop when not using an oil cooler. ---

Go by the fsm for the SR, it clearly shows a nice range of oil weights… it’s a good thing using a thicker oil in really hot ambient temps but I think 10w30 is fine all round. If I were to choose, I’d go for a 10w40… the last number being the most important since that’s the weight at operating temperature. ---

I’ll try a 10 40 next oil change mid summer. I’ll see how much higher my oil temp can go and still maintain 57 at 3250. ---
