NOTICE

Supply-chain disruptions have hampered our ability to restock items reliably. Many sought after parts are backordered without ETA info -- backorders with unreliable restock ETAs are VERY frustrating for us as well. We are doing what we can to adapt and recover from the changes to our industry, but currently many shipments are delayed and our response time to emails are slow (we are severely short-staffed). Even if we can't reply to your email promptly, please trust that we ARE working on getting delayed items back into stock for you, and we will contact you when we have any updated news. We appreciate your continued support and understanding.


When you place an online order request, you can opt to have in-stock items processed for shipment in advance of any backordered items. For out of stock items, you are NOT CHARGED, you are automatically added to the reservation waitlist, and we post stock status / backorder info to your Order Status/History Detail View in your online Customer Account. You can email to cancel un-shipped/un-paid items at any time as long as they are not special order or made/machined-to-order.

Please only continue if you are prepared to be PATIENT. Requested items could be delayed by supplier-level backorder, and we usually aren't given reliable ETA information. We work diligently to source and fulfill your request for items as best we can.

Amsoil Z-ROD 20W-50 Synthetic Motor Oil, QUART, ZRFQT-EA
Amsoil Z-ROD 20W-50 Synthetic Motor Oil, QUART, ZRFQT-EA


 
Amsoil Z-ROD 20W-50 Synthetic Motor Oil, QUART, ZRFQT-EA is one of the finest engine oils you can use for our Flat Tappet aircooled VW engines. This oil was designed from the beginning to provide flat tappet protection for our 1930s designed engines! We offer this 20W-50 for guys that insist on running this viscosity oil for their cars. This product can ONLY ship via Ground (UPS Ground, USPS Parcel Post, etc)!

AMSOIL Z-ROD™ Synthetic Motor Oil is specially engineered for classic and high-performance vehicles, and in our case that means our Vintage (Stock), and High Performance Aircooled VW and Porsches! It features a high-zinc formulation to prevent wear on flat-tappet camshafts and other critical engine components, along with a proprietary blend of rust and corrosion inhibitors for added protection during long-term storage. Z-ROD Synthetic Motor Oil is designed to perform on the street and protect during storage. Typically, the lifters and cam lobes on flat-tappet camshafts common to VWs, especially the high performance ones with heavier than stock valve spring pressures, slide rapidly against one another, producing high friction and heat. The friction between the two components can eventually wear down the cam and affect valve operation, ultimately resulting in lost engine power and reduced efficiency (OR ENGINE DISASTER!)

In addition, these areas are splash-lubricated rather than pressure lubricated like other areas of the engine, which adds extra strain on anti-wear additives like the zinc and phosphorus in zinc dialkyldithiophosphate (ZDDP). AMSOIL Z-ROD Synthetic Motor Oil is formulated with super-high levels of ZDDP to protect flat-tappet cams, lifters, rockers and other areas susceptible to wear. Its high-zinc, high-phosphorus formulation provides the extra wear protection these critical splash-lubricated components require.

Provides Long-Term Protection from Rust & Corrosion
AMSOIL Z-ROD Synthetic Motor Oil is formulated with a unique blend of rust and corrosion inhibitors to ensure maximum protection during long-term storage. To prove its effectiveness, AMSOIL submitted Z-ROD Synthetic Motor Oil to the Standard Test Method for Rust Protection in the Humidity Cabinet (ASTM D-1748). This test evaluates the rust-preventative properties of oil under high-humidity conditions, similar to those faced by a covered hot rod in a damp garage. The metal coupon treated with AMSOIL Z-ROD Synthetic Motor Oil showed no signs of oxidation after 192 hours, while the coupon treated with a leading competitor’s product failed the test after 24 hours.

APPLICATIONS
AMSOIL Z-ROD Synthetic Motor Oil is recommended for older or modified engines (which is our Beloved Aircooled VW and Porsche Engines) requiring either 10W-30 or 20W-50 motor oil. Z-ROD Synthetic Motor Oil meets API SL and earlier specifications, allowing for increased levels of anti-wear additives. ZDDP levels in Z-ROD Synthetic Motor Oil exceed the limits of API SM and newer specifications.

COMPATIBILITY
AMSOIL Z-ROD Synthetic Motor Oils are compatible with conventional and other synthetic motor oils. Mixing AMSOIL Z-ROD Synthetic Motor Oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL Z-ROD Synthetic Motor Oil.
