So I have a 2003 Nissan Sentra which was given to me by my family and it’s main issue is how much oil it is burning constantly. I find the car to be a lot more safer and reliable than my previous vehicle a 98’ ford taurus. I have my 1 year old son with me daily so his safety is my #1 concern especially when we are in the car so whatever I must do to fix this issue, I am ready though I am hoping to not have to replace the engine. The car is currently at 176,653 miles as of right now. I have done a lot of research on this issue in these past months and this is what i’lve come up with. I have seen a lot of blogs regarding similar issues that their nissan sentra was burning massive amounts of oil due to the manufacturer’s precat. It has been said to relieve the vehicle from its oil burning issue to change the precat to a header so one of my questions is would you find that to be the most reasonable answer, to change the precat to a header?? I was told the precat in my car had been changed previously so I inspected the car myself due to finding the mechanic had replaced the precat with another precat thus making no change to the issue at hand. I am getting really tired of feeding my engine oil when it just guzzles it down in a day or two. Here are some questions i have:
Would changing the precat to a header be the most reasonable solution to ridding this oil burning problem??
(if thats the case this would really relieve me over the stress i endure from this car)
I currently use SAE 10W 40 High Mileage engine oil; the owner manual says to use A) SAE 5W-30 viscosity oil for all temperatures & B) SAE 10W-30 or SAE 10W-40 if the ambient temperature is above 0*F so after using choice B, would changing now to SAE 5W-30 be a good idea???
Would it be a good idea to use an engine cleaner or some sort of cleaner to rid the excess oil from the engine?
Any comments or responses would be much appreciated!
