hi its me again. well i have so much time on my hands i came up wiht this theroy. since there are engine cleaners out there to flush oil why not do it another way. engine cleaners are sometimes bad on your seals. most of the time people who do use them end up with problems down the road. with that in mind why not just flush your oil, fill it up with some cheap clean oil. run it, and then drain it again?? you wont risk the fact that you are putting a cleaner with harsh detergents in the oil. you are just using an oil to basically "flush" what ever was left behind...what you guys think?
