Oil Additives?
#11
I don't hate Lucas, I hate their products.
Any Group IV or V oils. Brand makes no difference, they all have to meet the same standards.
Sorry, no. Your failed attempt at picking cherries won't work. ALL oils have additive packages in them unless they specifically say "non-detergent oil".
The reason not to use recreational additives is they may not be compatible with the oil's existing package. Reducing a desirable trait such as anti-foaming and shear resistance.
Which, has been proven before, actually happens when lucas is used with engine oil.

If thicker oil is your primary desire, why don't you use 20W50 or 15W50?
So what counts as synthetic
That's what the Exxon-Mobil sales rep said, but he also said it has an additive package, which would disqualify it from use in your engine.

Personally, I don't think it is anything to get too worked up about. While everyone likes to go gaga over group four (usually PAO or ester based oils, aka Amsoil, Schaeffers, Red line etc). Personally, unless you are running LONG OCIs (like 25k plus) or operating near the arctic circle I don't see how group fours are worth the outrageous premium they cost over a group III oil or a group II/II+ in a diesel engine. If your running a ferrari or an SR-71 or something like that it is a different story but regular old Delo or Delvac is fine for me and my operating conditions.
With respect to additives, I am not a big fan. Lucas oil stabilizer is nothing more than very heavy (125+ cst at 100*C, 40 wt oil is in the 13-16cST range at that temp), cheap base stocks (non-detergent) oil, unless your burning a lot of oil it is pretty useless IMHO.

Now it is more common place for companies to pass off group three products as synthetics (eg. rotella T6, Delo 5w40 etc).

OCI is a minor benefit, far from being its primary or only.

Synthetics don't have natural contamination like sulfur and carbon. Synthetics are also designed from the start to specifications where dino oils have to be cracked and use additives to get the properties they need.

Yeah synthetics have a great high temp and cold flow but they are not some holy grail of oils, group II, group II+ and group III actually suspend their additive packages better than group IV, so they are not perfect.

Personally, synthetics for me are a waste, my OCIs are too short, my engine doesn't get hot or cold enough for group 4's to have any huge advantage over a group II+ or a group III. I know some people like to get all hot and bothered over group three vs. group four but based on UOA's I have seen I fail to see group fours run away advantage in wear, or TBN retention or oxidation (sludge etc).
Anyways, to the OP sorry this is a bit of hijack of a thread about oil additives.
