Default Pennzoil Ultra 5W-40 Used Oil Analysis, 5997 miles, '04 FXT

UOA by Oil Analyzers Inc.

Driving conditions: Oil in use since Sep 2010; 7 mile daily commute each way; spirited driving with a few WOT's here and there on days where I have a 30 minute drive. In October, a trip to RI and to the White Mountains of NH (fun mountain driving). Most of my consumption is usually on trips if I'm driving on the Interstate at steady highway speeds. Temps down into the single digits F this past winter. Wear looks pretty good, IMO, although I did only go 767 miles after the last quart of make-up oil.

The last quart of make-up oil used was PU 5W-30. Went to the local Ferrari dealer and they didn't even sell PU 5W-40 since they use the Quaker State version. Ended up going to Wal-Mart to get the 5W-30.

Comments: Lubricant and filter change is suggested if not done at sampling time; Infared results indicate NITRATION is significantly high; Viscosity is SLIGHTLY LOW

Equipment make: Subaru
Equipment model: 2.5L Turbo
Oil use interval: 5,997 miles
Oil type & Grade: Pennzoil Ultra Euro 5W-40
Make-up oil added: 2 qts. (1 qt @ 2,037 miles into OCI; 1 qt at 5,230 miles )
Miles on unit: 105,639
Air filter: Amsoil Ea panel filter
Oil filter: Mobil1 EP

Overall severity of report = 3 abnormal

Nitration 27 27 32 27

I'm a little concerned about the nitration, but there really isn't much change over the past four OCI's. In between the run on SSO and M1 0W-40, there was one run on Red Line 5W-30 which I didn't have a uoa done on since it was right after a turbo failure at ~80,000 miles.

Considering switching to Red Line or Motul since I can get $100 off with my Subaru bucks. I'm thinking the esters in Red Line, 300V, or X-Lite might be ideal. I'm also thinking of just going with Motul Eco-nergy 5W-30 because of the high price of fuel!
