I have a topsider, and was planning on doing it myself. then i was at the quick lube in town for some tires, asked how much they'd charge if I brought my own oil and filter, and they said $7.00. that was a no brainer. However, I saw they had an even better deal $20 for up to 5 qts of syn oil, so add my other 3.5 and it'd cost me 41 plus a filter and I'm using the Fram filter also. May have to get a long term contract on this! having them charge me 7 for the labor ended up costing me still $70 for the oil and the filter vs about 52 the other way, buts still a heckuva lot less than the dealer charges!
