Rear main seal is very expensive to replace especially on a older car. So what remedies do you use for a small rear main leak? Do these seal stop leak additives work like Blue Devil rear main seal fix or others? Car does not burn oil at 4k-5k miles about 5 months) between changes the leak accumulates about 1/4 quart in the pan over change miles and time and the dip stick drop is about that . Infiniti I30 with 166k miles.

Thanks

what have you guys done for this?
