The new Gas To Liquid Base Stocks (GTL) are HydroCracked as well and they have amazing properties.Castrol Edge isn't syntehtic unless they changed recently.
Yes yes yes they put Syntehtic on the label. It's a load of ****, it's actaully just hydrocracking.
But it is dexosw by looks, so it will at least clean well. But I'm not sure about its properties.
This is correct. It's the sulfated ash content in the oil. The oil must meet minimum specification requirements to protect emissions control equipment. Is Castrol edge euro a dwxos2-compliant oil? If not, the OP will need to strongly reconsider their lubricant choice as it could end up costing them in emissions equipment failure.You might want to be careful running Euro oil in the Cruze. I'm no oil expert, but I believe something with the European additives aren't good for US spec catalytic converters. Hopefully one of the guys that know a lot about oil can chime in and help out. Is this oil Dexos certified by the way? That's an easy way to tell if its safe to use.
I will have to see how the OCI goes, like I said the engine sounds so much better its very surprising to be honest.You'll be fine. They are great oils, hence the controversial synthetic name. But the major difference between the Mobil1 and CE is that Mobil1 is PAO and CE is hydrocracked.
One of the reasons is because group 3 oils tend to absorb shock more than PAOs do. I've received reports of that many times over the years with some of our oils. It doesn't mean it protects better, simply that it absorbs more and is, in a sense "softer" of a base oil. It's hard to explain. Redline uses a similar approach in their shockproof gear oils.I will have to see how the OCI goes, like I said the engine sounds so much better its very surprising to be honest.
1. The semi-synthetic Dexos2 from the dealer for the first 4 free changesWhat were the three Oils?
Just a quick edit.
The Dexos 2 limit for Ash, Sulphated is .8 the Edge has .64 so all is well.

I am running the Amsoil now and will continue with that.
