First of all congrats for the oil write up. My vette was low on oil and changed it with one i found at the time. The closest was Mannol-5W30 fully-synthetic-oil
http://www.incarmotorfactors.co.uk/1...il-5-litre.jpg. Used same oil filter which i had because i could not find a replacement. Flushed it a couple of times with clean oil and re-put it in knowing i would remove this soon after. The car ain't a daily driver but was driven for 100 - 150 miles?) on this oil. Did a pair of sprints (when engine was hot) for say 2-3 miles with around 120mph top speed. it was 220deg to 240deg F i guess.
In our country temps are a follows:
- between 4 degrees (extreme cases) and 25 deg Celcius with nominal being 17 degrees Winter
- high rate of humidity in the country
- In summer the range is 23 degrees celcius and 34 degrees Celcius
should i use 0W30 / 0W40 or 5W30? and brand please? Mobil 1 or Penzoil? Very Worried!
