    https://www.epa.gov/gasoline-standards/gasoline-sulfur Tier 3 Requirement. So low- mid-SAPS oils less an issue here? (Is this old news?) EU has 10ppm sulfur limit: http://www.transportpolicy.net/standard/eu-fuels-diesel-and-gasoline/

    Car: 2013 Chevy Camaro Engine: V-8 6.2L LS3 Transmission: 6 speed manual Oil capacity: 8 qts Oil Pennzoil Platinum 5w-30 Euro L ACEA C3 Dexos2 I really like this oil. Held up well with 2 days for track use (about 200 miles at mostly full throttle). No oil consumption.

    PP 5w-30, Chevy Camaro LS3, 3800 miles

    I took this sample about mid way through draining the oil (capacity 8 qts) on a hot engine. Miles are approximate but should be +-200 miles of actual. OLM at 53% remaining. Edit: using ZL1 air filter with supposedly higher flow. Looks like no issues with filtration and it has been dusty due to...

    2007 Indmar Marine 340 EXT-CAT Rotella 15w-40

    This sample was taken at the 100 hour point, with 51 hours on the oil. Filter is a Wix 51039. I think the fuel dilution is normal for this kind of application. Indmar specs 15w-40 CI-4,SL. The engine is based on the GM 5.7 liter Vortec long block. 340hp driving through a 1:1 transmission and...

    Castrol Syntec Blend 20w-50 4427 miles '04 Disco

    This is the worst UOA I have ever gotten. The dealer uses this oil under the free maintenance program. My read is the 20w-50 is too darn thick for colder weather (oil in service Feb-May). The lead is present I believe in the cam bearings only, which would take time for the oil to get to on a...

    2004 Land Rover Discovery , Shell Rotella SM/CJ-42

    The new Shell 15w-40 CJ-4. I think they are compensating for lower additives with higher viscosity. These results are a little worse, though than previous samples with different oils. RTS is definately the winter call. Aluminum 5 Chromium 1 Iron 12 Copper 3 Lead 7 Tin 7 Moly 13 Nickel 6...

    2004 Land Rover Discovery 3604 miles Chevron Delo 15w-40

    Better results this round with Delo. This includes wife idling car for 40 mins and a lot of stop and go traffic. Night time temps about mid-60s. Also changed the oil with it still warm this time. Last round was after sitting overnight. All previous drains were with oil warm. Purolator filter...

    2004 Land Rover Discovery 3650 miles Chevron Delo 15w-40

    Not a great report. Used a Purolator filter on this round. It might be slower flowing than the OEM (I think Wix). The oil light goes out slower than I like at start up. I refilled with Delo, again with Purolator. Looks like Rotella and OEM filter might be best. Will also check for dirt ingress.

    Help with oil consumption / oil recomendations

    I'd use Mobil 1 Truck and SUV 5w-40, but search the UOAs section for like engines - several. Aside from that, the rings may not have seated properly. I would do some repeated acceleration/deceleration in 2nd starting at 2K rpm, mash the throttle until 5-6K rpm, then let off quickly; repeat...

    Is Moly a Friction Modifier?

    Does moly as an additive modify the friction properties of the oil or just act as a barrier lube?

    Clarification on Manufacturer's Oil Recs, 5w-20, etc.

    Although many folks (including me) have said that the auto manufacturer's must clearly recommend the grade used for CAFE, the roots are actually in the EPA rules. CAFE uses the EPA fuel economy tests for its basis. Here is the fine print in a letter to the manufacturer's. Look specifically at...

    Flat Tappet Cams Oil Rec

    I would appreciate your recommendations for an engine using a flat tappet cam. The engine is Land Rover 4.6 v-8. LR spec a 10w-40 weight oil as the preferred grade and are specific about using Castrol (no specific product, just the brand name, rated A2) in the US owner's manual. In Europe, 5w-40...

    Extended OCI? You decide....

    Engine is Land Rover 3.9L v-8 130K miles. It looked like this through the oil filler at around 88K when I bought it. Engine runs ok. The bearing shells were pretty worn when I changed them at 104K. The previous owner maintained the car at the dealer with roughly 7.5K OCIs. The dealer used...
