Oil Grade preferences for your LS3

[VFSV6FORME]

Without sounding like an ad; Mobil 1 is recomended even on the Corvette engine. Is a good GM qualified oil at a good price; no need for boutique type of oils.

Decisions, Decisions, and more decisions. All this Dexos stuff reminds me like what some say about Harvey Norman and you must buy FAT HDMI leads from them . Some will know what i'm talking about.

Castrol Edge 5w-40 is half price on 28th at one of the national chain stores (better not mention the store name here). I change oil/filter in between schedule services myself, so I am too fussy about getting the best oil. Any reasonable quality oil should be good enough for 7500 km.

Dexos 1 is nothing more than a standard that GM use to give the seal of approval and/or what oil manufacturer meet GM's requirements. I say, use any GM approved Synthetic oil. I stick to one brand for the sake of consistency. If I am looking for brand of oil as my next choice, would be Castrol Syntec. One type of oil that I will definite stick with is Synthetic.

Having never changed oil/filter on a VF SIDI six before I got a shock of the small size the filter is. The Filter that I was given from Supercheap was a Ryco R2605P and its a cartridge/paper only type of oil filter ( no metal around it). Now because of this I would expect that you would have a canister of some type where the cartridge fits/pushes into it and then you screw/bolt the canister back on.
Can Someone explain to me what I will find when its Oil and Filter change time?
How do you remove the canister or whatever holds this paper oil filter in?. Do you need the typical but small oil filter removal tool, Do you need a special size socket with a long extension bar to remove the canister or whatever hold that push on paper filter.
Any special other tools required for the removal of the oil filter.

Looks like I need a 24MM socket.

I have a 2016 Chevy Colorado with the 3.5 SIDI and have not changed the oil yet. The dealer gave me 2 free oil changes, will look into it after seen the video. Very odd place, same way like a Wankel Engine.

Have a VZ L98, VE L76 & my new VF LS3 run them all on Penrite 10-60 full synth no problems. Would not contemplate using any type of mineral oils in these engines.

In that list there's nothing over a 30 weight oil. No 5W40 or 10W40 so it must be largely a fuel efficiency thing, ie an oil which lubricates sufficiently while achieving good fuel economy.
Oh well I've been using 5W40 oil since before the Dexos ratings came out so I'm sticking with that as it's always worked perfectly for me. Seems a bit like DexronVI, I've used non approved ATF in my trans which runs better than the approved stuff ...

I was talking with a LS nut who uses liquid moly 10/60 & said his oil temp was consistantly lower than the Penrite 10/60 during track day sessions and swears it's the best oil he's run out of all the popular brands. I think I'm learning towards the liquid moly for my next service. Bloody expensive tho!
