I like 20/50 wt for year around....5-30wt is too thin but I use 0-40wt in my turbo Passat.

yes, 5w30 is too light, even in Illinois in January. Here in alabama I use 15W50. I think I've always read a 50 wt is right for an air-cooled engine, but I think 10w40 as a minimum should be used on your next oil change. You can overfill a 914 a little, up to 1/2 qt, but certainly no more. Too much will start leaking out somewhere- usually the valve cover gaskets. I try to put about 1/4th qt over the "filled"mark.

green light means less than 10psi of oil pressure.....
sounds like your low on oil. AA |

Holy sheep shit. I agree with Aaron! I overfill my oil a bit for spirited driving. Top mark and a little won't hurt. I use 10/30 year round without any oil consumption problems. Thick stuff scares me in the winter (SoCal) since my oil temps rarely exceeds 180.

20w-50 is real good...engine runs real sweet with it (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

One other thing to check is if the wire is firmly plugged into the sender on the top of the engine. I had a similar problem with the red light coming on at odd times. turned out that the wire was just sitting on the sending unit and was not plugged in.

according to the porsche manual, a slight flicker of the light at idle isnt of a grave concern......

Yup. OEM advises 30w over 32f. I'm no engineer, but doesn't higher viscosity oil circulate slower and provide less cooling? Could be my imagination, but engine seems to gain revs a bit quicker with 30w. Opinions??? I have a 2.0 with an aux cooler. Even at the track in summer it never heats up that much. Edit: I think the problem is more oil level in this case, anyway. |

then your not driving hard enough (IMG:http://www.914world.com/bbs2/html/emoticons/tongue.gif) i run 20-50, all 7 qts of it in my oil system..... (front cooler and big lines) hardly heats up..... lots of oil pressure when cold |

yeah but i dont think they had multi-viscosity oil back in the 70s...did they?
30w thins out.... 20w-50 stays as thick as 50w when warm.... best of both worlds.... b |

no... hear me out its like this 30w will tend to thin out as temp increases... a multi-viscocity tends to slow this process down.... example: 20W-50 at cold temps, this oil is EXACTLY identical in flow and viscosity to a straight 20W oil... but when hot, the straight 20W oil is now as thin as maybe a 10W when cold...IE thinner because of the heat while the 20W-50 is now as thin as a 50W straight oil when hot....hence multi-viscosity. so its like having a oil that's thin enough when cold yet thick enough at operating temp to keep on providing protection for your engine b |

OY! This is from my engineer? 7qts is a lot of qts for a 4. If you don't heat the oil to at least 180f contaminants will form; you won't burn off water vapor and unburned fuel. And I'll still beat you shifting at 5500 (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Viscosity |

85W-140 is what I use.....get natural stuff.... make sure you read the label.... look for something that says can be used for topping off limited-slip differentials only....topping off is the key word here. Limited-slip diff's require a special additive and since this product doesnt have this additive, the manufacturer advises against using it in a limited slip diff just by itself. This is good news for us. limited-slip diff's need extra friction modifiers and such, and therefore will not work very well in a transmission with servo-synchros.... GL-4 GL-5 stuff is fine, dont get fancy...again...additives are bad. SWEPCO is good from what i hear but too rich for my blood as a college student. this stuff is cheap and i can assure you my synchros work better than they ever have with this stuff.....i can speed shift now (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) b |

OK, quick test. With 20w50 oil, what does the 'w' stand for?
Think 0 and 100 Celsius (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |

at 0 degrees C, water melts and at 100 it boils...
so maybe it represents a range of avaerage temperatures oil is supposed to be designed for? For testing purposes and comparasion purposes...otherwise, if there was no standard anybody is right...... (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) |

Not a bad guess, but research and try again (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
