Is Castrol still one of the best anti LSPI formulas?

[PolarisX]

What octane fuel do you use?

93 only, usual Mobil but sometimes Shell.

 

[PolarisX]

It would have to be SN Plus to have the LSPI formulation. What's the bottle say ... just SN or SN Plus?

As others have mentioned, API SP is good for LSPI applications.

Just SN, the virgin UOA shows a ton of calcium as well.

across the entire lineup….probably shell honestly

I've asked this question in the past, and was told to stick with Castrol for the best LSPI control. Has anything changed in the last year and a half in that regard? I'm going to do my pre cold weather change soon and need to pick an oil, or just stick with what I've been using.

My main concern is my Cruze with the newer 1.4T that is VERY LSPI prone. I do have an aftermarket tune from Trifecta so I'm running a few PSI more boost than stock, picking up around 40hp or so. I do strict changes between 3 - 5k depending on what I have coming up, season, and if I've been short tripping or not. I've been running the Castrol EP 5w30, since its only a few dollars more than regular Edge.

Can anyone do what Castrol EP does better, in my situation?

I believe the answer to your query is PP Euro 0W-40!

I thought the recommendation from GM was to use a low calcium engine oil...the recommend Mobil (not necessarily or only Mobil 1) for this reason...

I've been using Mobil 1 (the regular 5W-30 Dexos 1 Gen 2 version) along with super unleaded (93 octane Costco Top Tier) since she bought her 2013 Malibu with the 2.0 turbo engine...if there is something better to use to minimize LSPI I'd like to hear it...

My brother wrecked a piston due to LSPI using M1 in his 2018 Cruze turbo. Had 6500 miles on it at time. I believe he was using 87 oct though.

Does the car call for 87? If not, then it's pretty difficult to blame anything other than operating error, lol.

87 oct is min

The pricing for SS is crazy though. I'd have to extend my intervals to make that work.

How do you acquire your oil from them? I don't have any local dealers near me.

Ooof, well, that's fun then. IIRC, Mobil was well ahead of the curve on producing LSPI-friendly formulations.

After doing a bunch more research I think my next OCI I'm going to try Ravenol DXG.

I use Amsoil products but I don't think you need anything more than a 5w30 SP Dexos approved oil or a 0w40 grade Castrol or Mobil1.

i guess it was not worth it.

how do you know it has been lspi? these events are very strong, can crack pistons.

 

[JohnnyJohnson]

Oil isn't going to do a thing for LSPI its just the way they shoved an engineering problem into the lap of the customer!

 

[silversport]

why does GM recommend using a low Calcium oil in the Dexos 1 Gen 2 rating then???...curious

Google 'Cruze cracked piston'. It's more preventative than anything.

I've only had one "event" I could detect when I first got the car merging. I heard a fairly loud crackle and an immediate loss of power. I've moved to 93 octane fuel and tuned since then and haven't had one since. When I got the car, I believe it was still just SN and not SN+ oil as well since it was 2017. Didn't see SN+ on shelves until early 2018. Dealer for sure sent me home with a tank of 87 octane.
