My car is going to be 7 years old in February and pushing almost 80,000 miles. Ive never used synthetic oil in it. Just synthetic blend (mid grade oil). I read mixed reviews on people when it comes to lucas oil stabilizer. Some people swear by it and others say its just snake oil. Would it be a good idea to start using it after every oil change or just keep going with my mid grade stuff and not worry about any additives?

 

i been using lucas oil stabilizer for 2 summers now and it really helps my engine, operating temps are consistent and hardly any valvetrain noise, reduced oil leak at main seal also noticed.



on the flipside, i don't use it in the winter though,



for a beta engine..which normally takes about 4 quarts, take a empty washer fluid jug, mix the bottle of stabilizer with 3 quarts of oil and pour in the engine.

 

Do not use on a good engine. This is not even a question.

80k miles is a baby. Be surprised if you don't triple that with regular oil changes at prescribed intervals. Use OEM filters from the dealer and Pennzoil Platinum synthetic oil.

 

if it's a low mileage beta, go with synthetic, but if you procured a cheap high mileage hyundai for $900 on craigslist, it's a helpful additive that's helped me in the long term during summer. before using lucas,i had to add a quart every 4 to 500 miles between fuel fill ups..really makes me wonder if i'm slowing changing my oil by adding more and more before my next oil change and only having to change the filter..



yeah, i saw the infamous bobistheoilguy pics of it foaming when they force emulsified it with air when they tested it at room temperature, but that doesn't simulate a engine at its operating temp which is around 180-190F

 

I'm betting you don't need to quintuple the viscosity by adding straight oil, even on a nearly-dead engine. If you want thicker oil at least buy a product marketed as engine oil with a full additive pack rather than JUST thick oil that dilutes the additives in a regular weight oil.

 

for once im with stupid.^^



i have a viscometer at school, i wonder what it would show for lucas

 

i originally started using lucas during summer is to slow down the oil leak, or at least until i change the main seal when i pull the tranny when the clutch needs to be changed,



but as stated earlier, i only use it during hot,warm weather, i run plain oil during winter, i know too well how thick the lucas stuff would starve our bearings at cold startup.

funny thing with lucas mixed oil is that the natural viscosity of oil doesn't seem to be affected, i mix it in my jug with fresh oil before pouring and goes in like reg 10-w30, same thing after draining the pan after cooldown.

 

I used it once. It was terrible. I had to drain the oil from my Bronco and replace.



Best case scenario you would still have been better off running a thicker oil.

 

did you mix the oil with the stabilizer?

 

Yeah. I followed the directions. The thing ticked like a time bomb.
