… this is not about a 914 but is about our 1977 911S Targa 2.7L
Took her in to have a bad ground fixed that was blowing a fuse on the clock/lighter circuit. While being serviced we had an oil change done although it didn’t really need it. We had 10L’s of Motul 20/50 added and new filter. While driving home I noticed that the oil pressure during throttle was almost pinned. When we got home (2 miles) the oil reading on the gauge at rest on level ground was just above the low line. This morning we moved it on the lift for winter storage and noticed a small puddle of oil, which never happens with this car. I cleaned the undercarriage and will see in the morning. Any ideas? |

20/50 seems pretty thick.
There are 1,000+ threads and opinions on oil. Do some research and change out the oil. My guess is pressure will return to normal with something a little lighter. |

My guess is pressure will return to normal with something a little lighter. Especially for winter season. It might take a long time for that oil to really get hot (and thin). |
