The only revolvers that don't count in your utilization are Charge Cards (like Amex Green, Gold, and Platinum) because they have no reported limit and must be paid in full every month.
The other thing that may be included in revolving utilization is a Line of Credit from your bank or credit union or a Home Equity Line of Credit (HELOC) less than 50k. If you have low balances on your cards but high amounts on these lines your overall utility will be shot. If you have a HELOC above 50k it is scored as an installment loan and impacts your score much less so.
