vs
Engine oil PENNZOIL or IDEMITSU
SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.
Pros: better LSPI protection
Vehicle:
Subaru
I buy 5 OE Toyota filters at a time from Amazon ( approximately $6 ea ) Purchase Ow-20 Idemitsu oil from NAPA ( ships free to my home ) in the cost saving 6gal box ( 24 qts ) for about $125 with their online coupon. Use this in both my Avalon and my Tundra- both run like a dream.
Pros: cars run like a dream, cost-saving
Vehicle:
Toyota Avalon
I use PUP 0w20 in mine. Lots of tests and UOA show that Pennzoil Ultra Platinum is the best non-boutique oil you can buy. But honestly any top shelf oil will work. 5k km intervals are more important than brand with a turbo engine.
Pros: best non-boutique oil
Vehicle:
Toyota
Mileage: 5000 km
Do her a favor a change the oil, with Valvoline Restore and Protect or Pennzoil Ultra platinum, it will quite down a little and it would be great for the car.
Pros: great for the car
Cons: requires oil change
Pennzoil Platinum Synthetic. My 1988 740 has near excellent compression at 245k og miles.
Pros: excellent compression
Vehicle:
Volvo 740
Mileage: 394275 km
At the very least, make sure you're using quality oil like Mobil or Castrol or Pennzoil.
Pros: quality oil
I use Pennzoil Platinum 5W-30 in my 2011 328ix (N51) I believe that is the recommended viscosity.
Pros: recommended viscosity
Vehicle:
BMW
I use 5w-30 pennzoil ultra platinum full synthetic with the oem motor craft oil filter
I change my oil every 3k miles
Vehicle:
Ford Mustang
Mileage: 4828 km
So if you review the virgin oil analysis database, it includes idemitsu 0w-20 and 5w-30 and for both, the TBN is rather weak in comparison to other more readily available blends, also, the viscosity at 9.5 cSt for a 30w, some 20w come close to that. Does any of that matter? Not a whole lot, but it shows that there's nothing special about the oil. Generally speaking, higher TBN is better.
Pros: nothing special about oil
Cons: TBN is rather weak
BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor
Cons: cause oil starvation
