Engine oil PENNZOIL or RAVENOL

Honestly I wouldn't have the guts to run it for that long. I run Pennzoil full synthetic with a Purolator boss filter and I still do changes every 5000 miles.

Pennzoil platinum high mileage full synthetic 5w-30. I work at a Toyota dealership and this is what we use and is recommended. It's flows well and has great wear protection. I used to use mobil 1 but this stuff is 10x better. If you do a little research it shows this stuff performs/flows better then most oils.

Pennzoil euro platinum LX 0W30 is the only readily available one that has the fiat/API approvals for the engine, advance auto usually has in stock at most locations.

I'm partial to Pennzoil Platinum Ultra 5w-30 based on UOA's at Bitog and other internet sources...

So, I recently drove 2 oils: NGN Emerald 5w30 and Ravenol VST 5w40. I watched the oil temperature displayed on the route book display in different modes, but there were no problems with the temperature.

I used Ravenol VST 5w40.

I bought this unusual oil made in Germany Ravenol NDT 5W-40...my truck has never sounded or performed better. I was hearing a little bit of top end noise at idle and that's complete quieted with this oil, as well as throttle response and overall smoothness of the engine and turbocharger increased greatly.

I’m using penz plat though I’ve only had my oil changed once (3500 on my OD) but so far so good. My oil temp stays around the 200 mark once fully warmed up and has been running very smoothly.

The data I've seen round the web, including BITOG forums says that Pennzoil Platinum and Pennzoil Ultra Platinum 5W-30 is as good or better than the waaay overpriced Motul stuff.

Motul xclean, amsoil signature series, valvoline max life, and penzoil ultra platinum are the favorites.
