Agreed, my mistake. Sorry OP.He said he was going to skip the additive and go with M1 15W-50, so I think he has learned.

And 4 stroke ATVs that rev to 9K and share the engine oil with the transmission and clutch.It’s funny how those HD 15W40s work okay in motorcycles that rev to 14,000 rpm, but aren’t suitable for a V8 at 7,000.
Do they really work ok though? Everybody I know that has run Rotella in motorcycles isn't actually the type to do any internal engine work. They think Rotella automatically equals high quality and just assume it's a great choice. Rotella is nothing special. It's oil made to a price-point to appease truck fleets with a cult following due to advertising.It’s funny how those HD 15W40s work okay in motorcycles that rev to 14,000 rpm, but aren’t suitable for a V8 at 7,000.

The car has a Lucas sticker on it.Skip the lucas snake oil for anything you use.
M1 15-50
M1 Euro 0-40
RP HPS series oils
I'd use it then.The car has a Lucas sticker on it.

Well... What more could you ask for?Cheap + engine didn't explode = god's gift to engines
People will go to great lengths to justify saving a buck. If Rotella was to suddenly go to $50/gal, they'd drop it in a hearbeat.
Paging @Foxtrot08 to give us the scoop on Rotella.Well...
What more could you ask for? Rotella is inexpensive, readily available, thicc, and has a decent add pack.

That's what I was thinking. If it is JUST an AX car I don't think I would want that thick unless there was some underlying low-pressure issue I was trying to band-aid. You don't usually get, nor want, a ton of warmup time. You could sit there and let the car run, but then you're heat soaked for the run and usually sucking in nice super hot air to the engine. I'd want an oil that can flow well on the colder end of the temp range, so I can start and go.For Autocross, you shouldnt' have oil temp issues, you beat on it for 50 seconds then wait 10-15 for the next run. Any basic OTS synthetic should be just fine. Quite different than 20-25 min of hard use on a road course.
Right. And that’s why I slipped in the 10W30 Delvac which has the same hths as some of the 0W40s @ 3.6That's what I was thinking.

Why a diesel oil at all? Why not just run Mobil 1 HM in 5W-30 or 10W-40? Or if the car is catless and some extra zinc is desired, then Valvoline VR1.Instead of 15W40 T4, better go with Delvac Extreme HTHS 4.1.
Delvac 10W30 has a hths of 3.6.
But the foaming requirements per ASTM D6082 are nearly identical between gasoline and diesel oils with an API license. In fact the diesel one is a bit more stringent.I'm very weary of diesel oils in gas applications. Gasoline oils contain more anti-foamer to match the general higher redline of gas engines, and I'm not sure why people would want to roll the dice on that.
Nice. 50 is insane for a water-cooled, low power density SBC engine. I would also not run a LL euro oil - too much detergent.Just bought this car that the owner modified over the last year for autocross racing - few small power mods and numerous handling mods. Owner says he's been running and racing it with Rotella T4 15w40 plus Lucas Oil Stabilizer. 1500 mile max oil change intervals. Says loads of racers use this same oil combination with great results. I'm thinking I'll just go with Mobil 1 15w50 and no additive. I think I'll be racing it this weekend at BRR SCCA 2023 Solo Championship Event #5
