For the Fiat 500 outfitted with the 1.4-liter engine and manual transmission, the manufacturer specifies a details lube type to ensure optimum transmission performance, longevity, and shifting top quality. Fiat Chrysler Cars (FCA), currently Stellantis, marks a certain technical spec for this transmission fluid. The right oil is a ** 75W-80 thickness quality, API GL-4 efficiency level ** gear oil satisfying the ** Fiat specification 9.55550-MZ1 **.

This specification is important. API GL-4 oils are developed for hand-operated transmissions and transaxles with synchronizers, specifically those making use of yellow steels (brass, bronze, copper) in their synchronizer rings. Utilizing an API GL-5 oil, frequently discovered for differentials, is highly dissuaded. GL-5 oils consist of greater concentrations of extreme stress (EP) additives, mostly sulfur-phosphorus compounds. These ingredients can rust the softer yellow metals used in synchronizers, leading to weakened moving performance, enhanced noise (whining, grinding), and ultimate synchronizer failing. The 75W-80 viscosity gives suitable fluidity throughout a broad operating temperature level array, making sure appropriate lubrication during cold begins and keeping adequate film stamina under high-temperature operation.
The gearbox ability is approximately 2.0 to 2.2 liters, though verifying the specific quantity through the automobile’s service manual is always recommended prior to embarking on a fluid change. The drain and fill plugs are located on the transmission covering. Constantly eliminate the fill plug initially before draining pipes to avoid the scenario where the oil is drained but the fill plug can not be loosened. Refill up until oil begins to leak out of the fill opening, suggesting the proper level. Utilize new securing washers on both plugs throughout reassembly.
Adherence to the given service intervals outlined in the proprietor’s manual is critical. While periods differ by version year and market, a common referral might be around 60,000 to 90,000 miles or 5-7 years under regular operating conditions. Serious solution problems– such as frequent short trips, stop-and-go web traffic, towing, or procedure in exceptionally messy, warm, or cold environments– might require much more frequent adjustments. Ignoring liquid adjustments allows deterioration of the oil’s lubricating homes and additive plan, raising wear on equipments, bearings, and synchronizers, ultimately running the risk of expensive transmission repair work.

Numerous reputable lube manufacturers produce oils meeting the Fiat 9.55550-MZ1 spec. Examples include Petronas Tutela Cars and truck ZC 75 SYN, Selenia FIAT 500 Gear Oil, and equivalent items from major brand names like Castrol, Mobil, Fuchs, or Ravenol specifically developed to API GL-4 and 75W-80 viscosity. When choosing oil, validate explicit compliance with Fiat 9.55550-MZ1 on the product data sheet or container tag. Stay clear of universal or GL-5 oils regardless of thickness cases. Making use of the incorrect lubricant kind risks instant and long-lasting damages to synchronizers and gear teeth surface areas. For outright assurance, getting in touch with the main Fiat workshop handbook or an accredited Fiat solution center offers definitive confirmation of the needed lubricating substance spec and solution procedure for the details automobile recognition number. Right lubrication option and maintenance are fundamental design methods making sure the transmission’s designed service life and operational integrity.
