My sister's car - 2002 Porsche Boxster 2.7L H6 Less than 100,000 miles. Only driven on Sunny days here in PNW, 2,000 miles/year.
Looking for engine oil recommendation for above. Last time she had the oil changed in Dec 2020, 2,000 miles earlier. The oil used was "European Syn 5W-40" no mention of brand of oil.
As stated, she only drives on nicer days with top down. Every cold start last few months, blue smoke comes out of tail pipe, none thereafter. Since the last oil change in Dec 2020, oil dipstick shows 1/3 below Full now. Looks like the Boxster is burning some oil, should I go for 10W-40 or continue using 5W-40? The ambient temp here is between 50 high, this morning was very cold at 25F, but mostly 35-40F. Thanks for your help.
Is Mobil 1 HM 10W-40, Castrol Edge or Liqui-Moly?
