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?

 

Thanks guys, you all really helped me out

 

 

Even tho Whargoul is a douchebag I do agree with him on this one about the only thing Lucas engine oil additive is good for is like the one guy said a derby engine or bar and chain oil for a chain saw although I would just buy bar and chain oil it would be cheaper

 

The Group Three vs. group four synthetic debate spurs from allow very processed hydrocracked conventional oils (group three) as synthetics even though they have effectively a dino base stock to them. Castrol and their Syntec line was one of the first companies in the US to pass off hydrocracked oils as synthetics, while in Europe the same product line is listed as a conventional. Now it is more common place for companies to pass off group three products as synthetics (eg. rotella T6, Delo 5w40 etc).

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.

 

Actually, no. Group 3 is still dino oil that legal loopholes allow to be called "synthetic". You can stick a duck call in a chicken's butt but it will never be a duck.

Notice, all are in the US. None of those oils are marketed as "synthetic" in Europe because they don't have that loophole.

Seriously, being directly lied to is no problem to you? Would you like to buy a 24k G0LD watch for $500? Its not real gold, but I can legally call it g0ld and charge the same price.

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

 

Reread my post, I never said group there were not dino based.

Honestly, I don't run group three or four synthetics in my truck and the performance difference from group three vs. group four is not a lead vs. gold difference. Does it really surprise you, in US we are the land of technicalities and run by lawyers...and group threes are usually a good 20% cheaper than group four counter parts.

Ok and most crude oil is not light sweet and therefore has a significant amount of sulfur in it, which is taken out during the refining process so it is useful as almost anything. CJ-4 oil limit the sulfated ash content anyways. So what the basestock had sulfur if it is taken out during the refining produces.

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.
