Agree, of course, it all depends on where you live and what temps you will be driving inIf you are burning oil at a fast rate would it not be better to use a thicker grade such as 10W30 conventional oil? This grade is thicker so it will slow the oil burning and reduce cost. Synthetic oil is great for extended oil change intervals but why pay a premium if it is not even going to last very long?
I think you mean "slightly decreased gas mileage"?Lucas thickens the oil a lot, depending how much you use. The heavy duty Lucas has viscosity at 100C of 110 cSt, the Synthetic one has 45 cSt, while the normal 5W-30 oil has like 10-12 cSt.
If you don't care too much about slightly increased gas mileage, I agree that's good stuff, especially for engines over 100k miles that have oil pressure issues (noisy at idle with hot engine) or burn oil because valve stems.
PS: Lucas makes a low viscosity additive (19.5 cSt), for newer cars: Low Viscosity Stabilizer
LOL, yeah, decreased. After all those years since I moved to "mpg", sometimes I am still thinking backwards in terms of consumption "liters/100km".I think you mean "slightly decreased gas mileage"?
I have two Fords with 19 year old / 190-200k miles engines and a 20 yr old Hyundai with 170k miles. All engines and transmissions still functional.o what? It's 14 years old with 180K, and burns oil!!!! Deposits, IF even possible, are the least of the worries.
I swear by Lucas products, had a new 2K Rodeo that "USED" oil from the start, weird because I never saw any smoke, I found the best way to help wasI swear by Lucas products. I have just over 100k miles on my '98 which Toyota recommends 5w-30. Since I've owned it (2007), for each oil change I add a 1/2 quart of -Lucas "Synthetic Oil Stabilizer" with Mobil1 0w-30 (synthetic) which Mobil says can be substituted for 5w-30 recs and I figure the Lucas stabilizer will thicken the oil just a bit. The engine still runs like new with no burning and no leaks and have yet to replace a seal (the timing belt, water pump, etc. service coming soon).
For your oil-burning vehicle, I would try adding a quart of -Lucas "High Mileage Oil Stabilizer" with or without a complete change and 5w-30 oil if you do (stay with the 5w-20 if you live in an icy clime). If you still don't see real improvement, you can try a quart of the -Lucas "Heavy Duty Oil Stabilizer" which will slow the burn, tho it's likely your piston rings and possibly internal bearings need replacing soon (assuming you're not leaking). .
If you're getting blue-grey smoke at start-up, you may have worn valve guide seals that allow seeping of oil into the combustion chamber while it's sitting (i.e.: overnight) -- I've heard it's sorta common on 1st-gen. RAV4's, not sure about yours.
You may swear by them but writing in all bold caps makes it seem like you're SWEARING AT us and won't convince anyone. I reduced your font but please do so yourself next time.I swear by Lucas products,
