Hi,
I have a 1997 Volvo S40 (normally aspirated 2.0 gasoline engine) with 200K miles. The engine still runs fine and I plan to keep the car as long as I can.
With such a high mileage I wonder what type of oil I should use. This engine is not powerful (140hp) and I don't race the car. I'm looking for an oil that can withstand OCI of 7,5K-10K miles. That engine only calls for an ACEA A3 rating and the possible grades are wide (usually from 0w40 to 15w40) with recommended 5W40 or 10W40.
Recently I've been running on Mobil Super S 10W40 which is a basic synthetic blend. But I'm unsure it can hold 7,5K-10K OCI (oil analysis are [censored] expensive here in Europe and it's not in my budget). Therefore I'm looking at other options which are:
- Liqui Moly Super Leichtlauf 10W40 (synthetic blend with normal OCI, rated MB229.1 and VW505.00)
- Liqui Moly Synthoil High Tec 5W40 (full synthetic for extended drain interval, rated MB229.1 and 229.3, BWM longlife 98 etc)
Obviously the synthetic seems better but it is slightl more expensive and honestly I do not know whether it makes sense to pour such a "good" oil in that standard old engine. Moreover what about running a 5W40 in a 200K engine??? That engine had 5W40 in the recent past but it did burn a bit more oil than with the current 10W40 so maybe the 10W is better than 5W for high mileage?
Also in Europe it is almost not possible to find a full synthetic 10W40 oil. All 10W40 are synthetic blends. Do you think the Mobil Super S 10W40 can cope with 10K OCI or is it too much? Would you recommend the full synth 5W40 over the synth blend 10W40 even if this means higher oil consumption?
Thanks a lot, I'm quite lost...
