I will be planning to start using the stuff on both my vehicles(01 saturn 1.9L sohc 44kmiles & tacoma 3.4L dohc 52Kmiles) next oil change and have a couple of questions.
1) My saturn has had syn in it changed every 4k miles since breaking 10k total miles and before that it had dino changed every 3k miles. The toyota has had sythetic in since i bought it(46Kmiles) but unsure before that. Would it be recommended for me to go ahead and do a clean/rinse on both or could I just start maint doses every change?
2) Say i do the clean/rinse program then go back to syn and 4-5k mile OCI's, will a maint dose from then on be sufficient for the life of the vehicle or will I have to keep doing the clean/rinse every 25K?
thanks in advance for the input.
