Choosing the right engine oil for your veteran, vintage or classic vehicle is essential for ensuring optimum running condition and maximum wear protection for your engine. To make selection easier, Castrol now produce a range of famous, classic oil grades and greases to the correct formulations and viscosities, as originally recommended by the vehicle manufacturers - though now using the latest technology, with low detergent formulations to better protect your vehicle. Many motor manufacturers originally specified Castrol in their handbooks and now you can follow those original recommendations. Castrol’s oil recommendations for vintage, veteran and classic vehicles date back to the turn of the last century and most of these are now captured in their excellent Classic Oil Finder database, a link to which is in each product description. Some very early applications as well as an interesting period explanation of motor car lubrication is attached as a PDF to the oil products as well.
