my girlfriends car is buring oil . she is needing the car to last until she gets out of dental school in a year. wondering if any of the oil additives would help slow how much oil its burning. ive looked at RESTORE, MMO, LUCUS heavy duty oil stabilizer. any of those help at all? she has been running 5w30 , we are going to use 10w30 next oci to see if the thicker oil will help. thanks for any advice.
