I just had this dilemma this morning. Tesco's own brand 10/40 oil at £2.98 for 5 litres, next to Castrol GTX at £12.98 for 5 litres. The label on the Tesco stuff says it meets the SJ standard.
No mid-priced oil in between, so what should I buy for a 1995 Cavalier
2.0i 16v, 98000 miles, which gets changes about every 6-7k?(this is a hypothetical question, btw: I got the Castrol.)
