Find the Red Line product for the job
Motor oil & racing oil
Start with the required engine-oil grade and specification. Compare street, Euro-Series, Professional Series and dedicated racing products by their current application data.
5W30 synthetic motor oil, 1 qt · 5W40 motor oil, 1 qt · 10W60 motor oil, 1 qt
Manual-transmission lubricants
MTL, MT-85 and MT-90 offer different GL-4 viscosity grades. Transmissions that specify GL-5 need a separate application check; the viscosity number alone is not enough.
Differential & specialty gear oil
Check the axle or differential specification, limited-slip design and any builder requirements. Standard 75W90 and 75W90NS have different friction characteristics.
75W90 GL-5 gear oil · 75W90NS GL-5 gear oil · Heavy ShockProof
Automatic-transmission fluid
Choose ATF by the exact transmission specification. D4, D6 and CVT fluids are separate products; do not select a substitute by brand or bottle size.
SI-1 fuel-system cleaner
Red Line SI-1 60103 is a gasoline fuel-system cleaning treatment. Follow the bottle directions and choose the quantity that fits your service plan.
Cooling & motorcycle products
Compare WaterWetter cooling-system additive, motorcycle engine oils and V-Twin drivetrain fluids. Match each product to its own system and the current service requirements.

MTL vs MT-85 vs MT-90 vs 75W90NS
Two bottles marked 75W90 can serve different applications. Match the API service class and friction requirements as well as viscosity. Red Line distinguishes GL-4 manual-transmission lubricants from GL-5 differential and transaxle products.
| Product | Grade / class | What to check |
|---|---|---|
| MTL | 75W80 / GL-4 | Manual gearbox requiring this grade; not GL-5 hypoid differential service. |
| MT-85 | 75W85 / GL-4 | The exact gearbox’s specified viscosity and lubricant class. |
| MT-90 | 75W90 / GL-4 | Manual-transmission use; not interchangeable with GL-5 differential oil. |
| 75W90NS | 75W90 / GL-5 | Specified transmission/transaxle use; lacks limited-slip friction modifiers. |
| 75W90 | 75W90 / GL-5 | Differential application; includes limited-slip friction modifiers. |
Have a modified gearbox, aftermarket limited-slip differential or competition build? Use the component builder’s fluid recommendation. A shared vehicle model or similar viscosity does not establish compatibility.

Are Redline oil and Red Line Synthetic Oil the same brand?
Redline oil is a common search spelling for Red Line Synthetic Oil. This page and the linked EDO Performance collection cover Red Line motor oils, gear oils, transmission fluids and additives.
What is the difference between MTL, MT-85 and MT-90?
These are Red Line GL-4 manual-transmission lubricants in different viscosity grades: MTL 75W80, MT-85 75W85 and MT-90 75W90. Choose the grade specified for the exact transmission. They are not substitutes for GL-5 hypoid differential oil.
Is Red Line 75W90 the same as 75W90NS?
No. Standard 75W90 GL-5 includes limited-slip friction modifiers. 75W90NS GL-5 omits those modifiers for applications that need different friction behavior. Match the transmission or differential specification before choosing.
Can I buy SI-1 in multipacks?
Yes. EDO lists the Red Line 60103 SI-1 15 oz bottle individually and in packs of 2, 4, 6 and 12. Confirm the pack count and current availability on the product page before ordering.
Does WaterWetter replace antifreeze?
WaterWetter is a cooling-system additive, not a substitute for the freeze protection required by a road vehicle. Follow the vehicle's coolant specification, the current product directions and any track rules.
