I am considering swithcing from the Doo Synthetic Oil. The smell makes me want to puke - even the new one. I read the previous thread about regular Doo oil, and I would consider that. Thre is another twist. In an old forum (can't remember if it was this one) people expressed disbelief that those of us with the new series 3 motors were getting 250-300 miles per quart of oil without problems. I have 500 miles on my 2000 Grand Touring 600 (hard miles) without any problem. I am getting 250-300 miles per quart. I checked with the dealer and he said the pump is set right. Is it safe to switch to a quality oil? Snow Tech had a favorable artical about Maxima TundraR. Very high quality/doesn't stink. If I recall, the regular Doo oil doesn't stink so bad. I hate to change when I have had good luck, but this smell is actually inconsiderate to other riders, not to mention myself. Thoughts?
