i have replaced the fuel filer! ok so switching oil is no problem for example original~~>blend then back to original (would there be any build up?)? oh i also added lucas--good or bad?! also the car ticks soooooo much when i stop... and sound from the engine....i leek about 2 drops every day becase the gasket is allittle loose(no big problem)......the car also begs sometimes to start, a month ago as soon as i turn the dam key bam it starts...(the weather just changed here in nyc!) now i have to hold the dam key...likes it is begging to start. fplease help thank u . ps How can i check knock sensor.......

 

i'd like to help you but you are some what confusing me. the fuel filter is for filtering out fuel, not oil.

did u use Lucas Synthetic Oil Stabilizer? or Lucas Heavy Duty Oil Stabilizer? eitherway, they are both very good. now the ticking is probably your drivetrain(cams and lifters) how many miles do you have on your vehical?

are you leaking oil or fuel? which gasket is a little loose? the oil pan gasket or oil pan drain plug? if its the drain plug make sure you change that copper crush washer everytime you do an oil change.

what type of oil are you using? if you not using 5w30 then start using it. it allows for a colder start because of the viscosity.

how to check knock sensor. take the harness and ohm it. match with oem specs.

 

wow man thanks for ur help .....i think i used heavy duty oils stabalizer...on my 96 max @ 60 K .....my car runs great and drink great also...i get bad mpg....as soon as the weather changed thats when the starting problem happen...i am useing 5w30 blend....wat is ohm ? And as for the leaking it is coming from the oil pressure *** where there is a wire connected ( i think i can change that) is there any way that i can check for computer errors? with out pay in a arm or leg?

 

ohm is resistance. there is a specification where nissan has for the part to meet. get a multi meter. go get your oil changed and just use strictly 5w-30. to check for computer errors you really cant. but if you are reffering to car problems the car's computer catches, then you should really check out this link
