Engine oil
Engine oil
I replaced my oil with 100% sand... it also added around 50hp.
Well how many miles on the car? how is the weather there? what type of driving do you do? I mean too many factors before just saying run this...

Ahhh yes... The eternal discussion. "Best motor oil." The only advice people can really give is to use a quality synthetic in a viscosity that matches the manufacturer recommendation, 5w-30 for climates that get cold in the winter, 10w-30 for ones that don't, unless you have reason to use another (some people do, but most don't). I'm a Valvoline guy, my neighbor only uses Mobil 1 products, my other neighbor buys whatever is on sale, several people here swear by Castrol, and still others live on Pennzoil. Truth is, they all get the job done. The differences between the consumer grade oils are generally pretty small, especially if you are not going for extended oil drains (10K-15K miles between oil changes). We are really talking about eeking out 1% differences here. Over a hundred thousand miles those 1% differences add up, but the 1UZ-FE engine in your SC4 is a quality engine and won't even notice. The full PAO synthetics, like AMSOIL, Royal Purple, and other specialty or "boutique" oil suppliers, might be more than 1%, but for the off-the-shelf oil, pick one that is a name brand oil and use a nice quality oil filter (e.g. not the lowest grade FRAM) and change it according to manufacturer recommendations and your SC engine will run for a quarter million miles or more. Mine just hit 200K and still running strong. 
Keep in mind that the Lexus "normal" service schedule specifies 7,500 miles between oil changes. However, most people don't fall into the "normal" service category. It's kind of a misnomer. Unless you drive mostly highway miles, your driving is "severe" service, which requests 5K mile oil changes. Toyota/Lexus and consumers found this out the hard way with the sludge/gel issue in the 3.0L and 3.3L V6 engines.
