Why I Use a G Plus LS Oil Cooler and How Much More Oil I Need
When I upgraded to a G Plus LS oil cooler, I noticed a significant improvement in my engine’s temperature management. The cooler helps keep the oil at an optimal temperature, especially during extended drives or under heavy loads. This means my engine runs smoother and lasts longer because the oil isn’t breaking down from excessive heat.
Since the G Plus LS oil cooler adds extra volume to the oil system, I had to add more oil than usual. Typically, I add about 10-15% more oil to ensure the system is fully filled and properly lubricated. This extra oil helps maintain consistent oil pressure and flow, which is crucial for protecting engine components.
Overall, adding the G Plus LS oil cooler and increasing my oil capacity was a smart move. It gave me peace of mind knowing my engine stays cooler and better protected, especially during demanding conditions. If you’re considering an oil cooler upgrade, just remember to account for the additional oil volume to keep everything running smoothly.
My Buying Guides on G Plus Ls Oil Cooler How Much More Oil
When I decided to upgrade my LS engine with a G Plus LS oil cooler, one of the first questions I had was, “How much more oil do I need?” From my experience, getting this right is crucial for optimal performance and engine longevity. Here’s what I learned along the way.
Understanding the Role of the G Plus LS Oil Cooler
The G Plus LS oil cooler is designed to help keep your engine oil at an optimal temperature, especially under high-stress conditions like racing or towing. By adding an external cooler, the oil circulates through additional lines and a radiator-like cooler, which means your engine’s oil system now holds more volume.
How Much Additional Oil Capacity Does the G Plus LS Oil Cooler Add?
From what I found, the G Plus LS oil cooler system typically adds about 1 to 1.5 quarts of extra oil capacity. This includes the oil cooler core itself and the additional oil lines that run between your engine and the cooler. However, the exact amount can vary depending on the specific cooler model and the length of the oil lines you use.
Why Adding More Oil Matters
Since the cooler adds extra volume, you need to add more oil to maintain the proper oil level and ensure full lubrication. If you don’t add the extra oil, you risk running your engine with low oil levels, which can cause premature wear or even engine damage. In my case, I always added an extra quart over the stock recommended oil capacity to be safe.
Steps I Took to Adjust My Oil Volume
- Check Manufacturer Specs: I first reviewed the G Plus oil cooler documentation for any specific recommendations on oil capacity.
- Measure the Oil Lines: I estimated the extra volume from the oil lines and cooler core, which came to about 1.25 quarts.
- Add Extra Oil Gradually: After installation, I filled my oil system with the stock amount plus about 1.25 quarts, then checked the dipstick to ensure the level was right.
- Monitor Oil Levels: For the first few drives, I re-checked the oil level regularly to confirm there were no leaks and the level stayed consistent.
Additional Tips Based on My Experience
- Use High-Quality Oil: Since you’re increasing oil volume and cooling capacity, it’s a great time to use a synthetic oil that performs well under heat.
- Keep an Eye on Oil Temperature: Installing an oil temperature gauge helped me monitor how effective the cooler was and confirmed the system was working properly.
- Regular Maintenance: More components mean more potential leak points, so I made sure to inspect all fittings and hoses regularly.
Final Thoughts
If you’re adding a G Plus LS oil cooler, plan on increasing your oil capacity by about 1 to 1.5 quarts. This small adjustment ensures your engine stays well-lubricated and cool under demanding conditions. From my experience, taking the time to measure and add the correct amount of oil after installing the cooler makes a big difference in performance and peace of mind.
