How long can a generator run before adding oil? No run time is stated for the generators these kits fit, so the answer comes from the dipstick and your generator’s manual, not from a fixed number. Check the oil level before you run the generator, and change the oil with a kit matched to your generator when the level is low or the oil looks dirty. This guide shows how to check the oil, what the kits here cover, and how to match a kit to your generator.

How long can a generator run before adding oil: the quick answer
The short answer is that no run time is stated here, so do not run on a fixed clock. Check the oil with the dipstick before each run, and add oil or change it with a kit when the dipstick shows the level is low. Generators run outdoors only, far from doors and windows, because of carbon monoxide. The kits below cover the oil change itself: oil and a filter for Generac and Kohler generators, a full tune-up kit for Onan RV generators, and a funnel and magnetic dipstick for the Honda EU2200i.
Step 1: Check the oil with the dipstick
The dipstick is the measurement that decides whether to add oil. The Kujunpao kit (on Amazon) pairs a magnetic dipstick with a funnel for the Honda EU2200i: the magnet at the tip captures and holds metal chips and particles in the oil. Pull the dipstick, read the level, and wipe it clean before you put it back. If the level is low, add oil; if the oil carries metal chips, the magnet shows them on the tip.
Step 2: Add oil or change it with a kit
When the dipstick shows the level is low, add oil through a funnel so it goes where it should. The Kohler kit (on Amazon) includes an oil funnel for adding oil or for use when draining oil, and the Kohler and Generac kits include an oil absorbent pad to prevent spilling on floors and other surfaces. A kit change means fresh oil and a fresh filter together: the Generac kit (on Amazon) has 2 quarts of 5W-30 oil and a filter, and the Kohler kit has 2 quarts of 5W-30 oil and a filter. For an Onan RV generator, the ATRACYPART tune-up kit (on Amazon) covers the air filter, oil filter, fuel filter and spark plugs in one pack. Match the kit to your generator brand before ordering.
Step 3: Match the kit to your generator
Oil change kits fit specific generators, so match the kit to yours before ordering. The Generac kit is a 5W-30 oil change kit with a 70185E oil filter, and the Kohler kit is a 5W-30 oil change kit with a 12 050 01-S oil filter. The ATRACYPART tune-up kit fits Onan RV QG 5500 and 7000, Marquis Gold and Marquis Platinum QG EFI, and models HGJAA, HGJAB and HGJAC, with an air filter, an oil filter, a fuel filter and 2 spark plugs. The Kujunpao funnel and dipstick fit the Honda EU2200i. Check your generator model against the kit before ordering, and check the filter part number too.
Ways to keep the oil clean
- Check the dipstick before each run, and wipe it clean before you put it back.
- Use a funnel when adding oil, and keep an absorbent pad under the generator when draining oil.
- Match the kit to your generator model before ordering, and keep the filter part number with the kit.
- Change the air filter, oil filter and fuel filter together when the tune-up kit fits your generator.
The gear for this job
The dipstick check in Step 1 and the oil change in Step 2 need the right kit for your generator, and the 4 kits below cover those steps.
