Semi synth oil in Golf Gti 09
« on: October 24, 2019, 07:55:29 pm »
Evening. I have stupidly put 5-30w semi synth oil in my Golf Gti which has 5-30w Synthetic oil in normally. It was getting low and I poured the semi synth in thinking it was synthetic. Only just twigged 5 days later when I was looking to put oil in wife's car. Is this going to cause problem and what should I do? Been 10,000km since last oil change.

Check the oil specs some can be mixed. If you have done 10k time to change anyway.

Thanks mate. False alarm, it was fully synthetic I used. Had both in the garage and I used the gold bottle of Castrol Edge. Panic over. I usually get the oil changed when servicing at 15,000kms
