Ford Focus Mk1- What engine oil do I use? 

I'll keep you posted bud thanks for the shout out👍🏻 next big job now is getting that knackered engine out and just salvage what I can for spares rest can get scrapped.

Another useful video here on what to use. Thanks 😁

Mate that's one clean engine bay. Well impressed

Man, I am so jealous of your coolant reservoir.. On topic: I have 1.8 Tddi focus. Now it is third oil change that I do with same filters and oil. I do use 5W40 Castrol turbo diesel titanium with mann filters. I chosen 5w40 because i have 270000km (around 167k mi) done and I change every 10k (6k miles). I don't even need to look at dip stick, because it does stay where I left. Also, they say diesel oil always black. Well after this change I done around 4k and I can still see a bit of amber color. Really, don't cheap out on maintenance and even old tddi will last forever!

I tried everything, Liqui Moly, Motul, Castrol, Shell Helix, Total, with everything I had oil consumption! at last I put the Valvoline Synpower in, and now I don't have any oil consumption anymore, and the engine runs very smooth!

Always had oilf change on my Mk1 every year as the interval was 12500 mile or 12 Months

Ive got Y reg focus 1.6 zetec, ive done nearly 50,000 miles in it in 3 years since i bought it, only paid £300 for it, its been a brilliant car without issues, apart from a water pump and usual mot things, but ive never changed the oil, just topped it up now and again, its on 129,000 miles now, maybe id better drop the oil and put fresh in it, the engine sounds smooth no tappet noise even on cold start, dont want to ruin it , as you've showed us in that clip what can happen to the bottom end, great informative video as always

Is it normal for the bite to be near the top on the clutch? My car judders as well so I have to accelerate a bit to stop it juddering. Is my clutch on the way out?? Also my engine makes ticking noises, any suggestions?

What product do you use in that engine bay to make everything look so new

I used 10w40 since 2015 in my focus 1.6 zetec,manual says it can be used had no problems tbh

I'm a fool maniac, I guess.. I think oil change is the most important maitenance in a car's engine. I use synthetic oil, change interval is six month (or 8000km, whichever comes first). My maniac method is: round one: old oil plus engine flush (Liqui Moly), 10 minutes idle. round two: New filter, new cheap oil plus engine flush (Liqui Moly), 10 minutes idle. round three: New cheap oil without engine flush, 10 minutes idle. round four: New filter, new synthetic oil. Good to go. I use the round two and round three oils in the next change, six months later.
