What do you think of oil Additives?

[Aceventura9586]

Don't jump on me if it was already said in this post, cuz I didn't feel like reading all the posts.
But doesn't the owner's manual in our cars specifically say to not use lucasoil additives?

Like in my Camry with 180000 miles, I use the 10w40 half synt. on my gen 6 camry with 33000 miles.
Here in Holland we drive a lot on LPG. This mean liquit petrol gas.
why are we doing this: one liter normal gas costs 1,24 euro p/L LPG costs 0,42 eurocents p/L.
I don't know if this fuel is available for America. For this fuel there's an extra tank built in and extra injectionnozzles. This all is powered by an extra computer.
With LPG the burning temp. is higher than normal gas. Therefore I use the Flash lube system. Is this known in America ?

It seems LPG (propane) was used here in Canada (80s?) by vehicle fleet owners such delivery companies, the armed forces, taxis etc but I don't see it any more. I did drive a small truck at one point that used propane, I remember it using about 30% more propane then the equivalent volume of gasoline for the same mileage. There was some issue with the pressure regulators freezing up as the liquid turned to gas passing through them. New regulators were installed that had engine coolant circulating through them too to help prevent this. Here propane is mostly used for barbeques, camp stoves, equipment and home heating where natural gas is not available.
The prices you quote for gasoline ( a Euro is worth at least two Canadian dollars?) are offensive, so even if LPG delivers 30% less mileage you are still way ahead using it. I am not familiar with the flash lube system.

New regulators were installed that had engine coolant circulating through them too to help prevent this. The trucks also had some other calibrations done to them if they were converted from gasoline, including the installation of distributors with a different timing curve (before computers), overheating was also an issue. It is supposed to burn really cleanly. Here propane is mostly used for barbeques, camp stoves, equipment and home heating where natural gas is not available.
The prices you quote for gasoline ( a Euro is worth at least two Canadian dollars?) are offensive, so even if LPG delivers 30% less mileage you are still way ahead using it. Gasoline here is now down to $.72 a litre from $1.39 a few months ago, gotta love this failing economy..

Thank you for your answer.
Lpg is no Propane. Lpg is a kind of gas what's a rest product by fabrication normal gas. In my tank its liquit. The burning tempreture is higher than normal gas. Therefore I use flash lube. I heard that flash lube is used a lot in australia.

I always use brand name oils of the recommended grade with the API symbol on them. I have opened up a few of my old V-8s to change timing chains or valve cover gaskets and found everything to be nice and clean inside, I have never had an oil related failure. I have used some engine flushes when, after purchasing a car I felt the oil was quite dirty and the engine might be gunked up, but I'm not crazy about running an engine with the oil thinned out by something similar to varsol etc.
An old real-world study by Consumer Reports revealed that additives make no difference on engine wear, they only found measurable differences in engine wear when no-name oils were used without the API symbol, of course there was slightly more wear but nothing to cause an engine failure. The tests were conducted on NY Caprice taxi-cabs with 4.3 litres V-6s.
They also make a case for using synthetics when temperature extremes are involved.
I am glad to see the info on the oil filters, I had mostly always been using Fram, with this car, I use dealer filters.

I haven't heard that word varsol since I was in Auto Mechanics!! Thanks
