Hi I'm about to buy my first Skoda, so new to the forum I'm looking to buy an used Octavia hatch - likely a SEL or SE Tech, with a manual box - most likely a 2017 or 2018 model (post-facelift) I'm trying to decide between a petrol or diesel, and have narrowed my choice down to a 2.0 TDi or the 1.4 / 1.5 TSi, and wondered if anyone could offer any advice on which to buy. (I do about 10,000 miles / year - generally on long runs / motorways, so could justify either). I quite fancy a petrol, buy am drawn by the fuel economy of the diesel ! I'd be grateful if anyone could offer any advice on: Is there much to choose between 1.4 and 1.5 TSi petrols ? Are these 2 engines similar? (I think I read once that there were reliability issues with one of these engines?) What is the gearing like on the petrol v diesel. How many mph per 1000 revs does the petrol / diesel give in 6th gear? I wondered whether anyone can give any advice on how the petrol drives v the diesel ? Which is the most fun and easiest to drive? Is either the petrol or the diesel much quieter or more refined - and the more relaxed motorway cruiser? Does the additional weight at the front end affect the handling of the diesel v. the petrol ? Thank you in advance - any advice is very much appreciated ! Tarquin
