Powerboost engine oil?

[Samson16]

I see no direct correlation between low speed pre ignition and your choice of engine oil.
Low octane fuel under too much pressure is the primary cause.

The rest is just marketing hype around the margins.

I am a newbie to the ecoboost but what makes it go boom is not the budget oil you change every 5k miles

Thanks for the post and the education. What is LSPI?
I’m running Motorcraft full synthetic 5w30(not the blend), and a Motorcraft filter. I change both at or before 5k.
How am I doing?

ps: word of the day Tribology

full synthetic, in the us, is a misnomer. Aka lie. A group III oil, in the us, can be labeled “full synthetic”. Top level amsoil and all redline are group IV’s or V’s..

Penzoil platinum is is created in a way that makes its “full synthetic” reasonably good, and mobile simply enginers a good oil. yet both are group iii’s.

motorcrafts oil? Don’t know it. So long as it’s an api sn+ or better it’s not bad. You can do better on the filter. I don’t rememer who makes their filter anymore, but it’s not fantastic. that said I’ve never seen a “bad” motorcraft part.

OCI is more about how things are used, but in general 5k miles is plenty safe. I suppose we go closer to 8k miles.

that would be very wrong, and I’m used to seeing better posts from you. plenty of research done on it throughout industry. i politely suggest you read more on LSPI as it appears in this case your misinformed. Or maybe just confusing it with run of the mill preignition.

here is a start for some reading:

I’ve been using m1 euro 0w40 in gm ls and genv LT motors for years. It’s a great oil.

I thought it would be excellent for turbo bearings but I wasn’t sure how it stacked up to gf6 oil for lspi. Also how it would work on a hybrid 3.5. Thoughts?

api SP >\= gf6, so all is well. Given these newer oils help chain wear/stretch(kind of a misnomer), they are great fits. It’s certainly what I would use in a PB. It’s in the eco 3.5 right now. if you look at actual temperature/viscosity curves it’s only different at the temperature extremes. Like if you’re running hot (like say a turbo bearing). Or super cold. Since startup is when most wears starts….

Not a Ford but the wife’s 05 Pathfinder we bought brand new in 06 with free lifetime oil changes from the dealer just had the valve covers and gaskets replaced. Mechanic sent pics to me and asked if this was original motor. ? I told him everything else has been replaced, but the motor which is literally true, changed oil every 3k and we just clocked 277k on it. I thought it was impressively clean in there.

That. I don’t understand the boogeyman.

That’s the spec sheet for the oil I’m using.

Motorcraft oil is ConocoPhillips - It’s a good oil. Even the semi synthetic isn’t bad. I use Pennzoil Platinum and for reference per this data sheet you attached the flash point is lower on the Pennzoil, which is a win for MotorCraft. I will continue to run Pennzoil Platinum 5W-30 forever at this point as that’s what I’ve fed my 5.0 since day 1. Don’t want to switch the additive pack now. That’s not to say other oils aren’t better.

I'll be a little less critical of your point.

LSPI is a term that has been given life in order to differentiate it from "ordinary run of the mill pre ignition", as it was described.

But it is pre-ignition and no oil exists that can eliminate it. Certainly not on its own.
And I completely agree with you that since oil is a participant in LSPI, it affords the oil products yet another attribute to tout on their container.

So if I am driving in a school zone with 93 octane fuel and experience hard spark knock that’s LSPI caused by going cheap on my oil? I don’t understand.

I don’t think the 3.5 is going to experience that, especially on premium. You guys are running a relatively low static compression, so in times of low boost I wouldn’t worry. There were many reports of the last gen 18-20 5.0 knocking on 87 octane in such situations, but none I’ve ever seen on the 3.5 EB to date.

Thanks. I’m deliberately asking stupid questions because I don’t understand the difference between spark knock due to low octane fuel and spark knock due to low octane fuel while running cheap oil?

 

[TheGoatman]

There’s plenty of published literature on it. The best anyone can do here is regurgitate that due to the newness and complexity of it.

it doesn’t have to do with expense but elements in the oil. A lot of Cheap oils were reformulated to reduce the effect

 

[Snakebitten]

I'll add to the last couple of posts that if you are using one of the modern "reformulated" oils, and buying fuel from a station that sells a lot of fuel (fresh fuel, clean tanks, and hopefully good filtering), then you can TRUST the Gen14 engine management to do the rest.

Although I personally "trust but verify" with an OBD dashboard.

Remarkable engine, regarding.

 

[Samson16]

Ok. It’s obviously something that occurs/occurred to a statistically significant number of gasoline powered vehicles to warrant a change in oil formulation. I am checking my dubious ? bent, and will read up on it. Something about undesirable particulate matter catching fire…
