Oil=power Options

[Milds3vn]

I was wondering if the fact that i put full synthetic Synpower in my car increased performance a bit? The engine seemed to smooth out alot after i changed this in. How low can the oil get on the stick and still be safe? The oil is a bit more expensive but doing that and always using 93+ gas it feels alot better in general. I have an exhaust too but I got a K&N not to long ago which seemed to help feel a gain from it, does that seem right or is it just cause i think its helping. If you don't have much money for mods i would suggest better oil, gas, and a filter. All cheap enough and unless im wrong, i think it has made a big difference. I have like 95k so maybe the synthetic helps "restore performance"? What about those engine oil aditives from Valvoline and STP, do they help? I have been wondering about this stuff for a while and feel like knowing for sure. Thanks for whatever anyone knows.

I've owned my 95 ST for 4 years now. It had 89k on it when I got it and I've been putting 93 octane gas with Castrol Syntec 5w30 since I bought it. Now I've got 187k and have had no mechanical problems.
All that has been replaced:
- Timing Belt (120k)
- Battery (130k)
- Starter (130k)
- Plug Wires (140k)
- Plugs (150k)
- Clutch (150k)
- Fuel Filter (180k)

The 93 and synthetic will help the engine run smoother, and the synthetic will add power(just not much, maybe 1/2 hp). As far as mileage, I get 33mpg in the city and about 28 highway. It goes down on the highway because of how high the rpms get when you go 80+.
