Phil Posted October 24, 2001 Share Posted October 24, 2001 It refers to the 'weight' of the oil when cold and hot. Best bet for the Supra is a nice fully or semi-synthetic but not Mobil 1 0-50w as it's too thin. A common choice is Valvoline synpower 5-50w fully synth, you can get it from Shop!

Simon Posted October 24, 2001 Share Posted October 24, 2001 All information copyright Exxon Oil and can be found on http://www.exxon.com/exxon_lubes/superflo/pgtigertips.htm. (That 'W' stands for winter; and the lower the number before the 'W,' the lower the temperature it can handle.) But please keep in mind that this '5' or '10' number has nothing to do with the oil's performance at operating temperature. Once your oil has warmed up, the viscosity (or thickness) of a 5W-30 oil is about the same as a 10W-30. In short, a well-made 5W-30 oil performs better in the cold, with absolutely no penalty in performance after the oil has warmed up. Your engine oil not only Lubricates, it also... Prevents wear Cools parts not reached by your cooling system. Keeps your engine clean. Neutralizes harmful acids and other contaminants. Reduces friction (for fuel economy) Seals the piston rings and cylinder walls (for better oil consumption and performance) With so much at stake, you should really choose a good oil.
