semi synthetic V mineral oil ...
what are the real world problems on switching between the recommended 5w 30
synth blend oil and 10w 40 mineral oil in a car? I want to use up a load of 10w 40 mineral oil in it. What is likely to go?...Bearing in mind it will only be used for six months in the summer. |

Viscosity-wise, some - especially those that require thin oils like 5w30 - can have all sorts of problems if used with thicker oil. Base-stock-wise, again depending on the engine, there shouldn't be any great difference between mineral and semi-synth, except you'll want to change it more quickly. If it's a turbo, though, I really wouldn't - the heat of the turbo may very well cause it to carbonise in relatively short order. For the price of even five litres of mineral (so cheap) oil, why risk it? Just chuck it on freecycle or in the lawnmower or even take it down the tip. |

So, yes, the recommended oil may well be specced for cold winters and - in a car sold in the south of the US - hot summers. |

The Ford 'Essex' is a dark ages technology engine The Canadian Essex is totally unrelated to the European Essex... and I'm amazed anyone thinks it needs synthetic oil. There's "needs" and there's "will benefit". Ain't such a thing as an engine that won't benefit from better quality oil. |

Scott very reassuring...thanks...yes it has two camshafts in the block. Err, no. The Essex is a single camshaft, pushrod engine. I can't remember what oil I put in a my Mk1 Capri 3000S (too long ago), but it won't have been synthetic, partly because I suspect it wasn't available & partly because I wouldn't have been able to afford it. The Essex was produced in many guises some of which were overhead cam - mainly for performance cars. Essex was really the name of that particular block - a V6 block originally, then a V4 in some guises. a good intro to ford production engines is here http://en.wikipedia.org/wiki/List_of_Ford_engines The notorious OHC camshaft breaker was the pinto engine. -- New Socialism consists essentially in being seen to have your heart in the right place whilst your head is in the clouds and your hand is in someone else's pocket. |

Last time I saw a car with 3000 mile oil change intervals was in the '50s, and it had by-pass oil filtration, and white metal bearings. The same engines changed to full flow (as all engines from the mid '50s did to allow modern bearing shells) moved to 6000 mile oil changes. -- *IF ONE SYNCHRONIZED SWIMMER DROWNS, DO THE REST DROWN TOO?
