I'm a big fan of the Pennzoil Ultra that has hyper cleansing technology and what I've been using in the FX50S for a long time. Great for our engines considering ours break down the oil and get dirty faster than other cars.
This oil smokes mobil 1 and Royal Purple.....and matches Amsoil Signature Series on paper, so it's a bargain for the quality of product.
It is an outstanding oil with exceptional specs. Ultra has extremely low NOACK volatility percentage of 6.6% for the 5W-30 (Mobil 1 is 10.1%). Lower percentage is better. Great cold temp performance, ridiculously great showings in the Sequence IIG piston deposit and Sequence IVA camshaft wear tests, carries all the certifications, and even comes with a 500,000 mile warranty with this oil. It's based on a relatively new GTL Fischer-Tropsch, which is a big part of why it performs so well.
Mobil 1 extended high performance filter (not the regular one) or the bosh premium distance plus (not the regular one) I will use. Both are considered top and depending on where I'm at I will get one of these. You get top notch filtering without reduction of oil performance like you would when using the higher end purolator.
