DougH 270 #26 June 4, 2007 Quote You dont necessarily "have to" but different oils have different viscosities and break down at different temperatures and lifespans. Its just a piece of mind sort of thing. Its ultimately up to you but it wont make much of a difference. Where did you go for your automotive training? The type R vtech school of NAWSSSSS?!?!?!?! On a side note if you drain synthetic at the regular 3k interval you aren't taking full advantage of it and you are simply wasting cash. It is designed for much longer drain intervals, but I recomend changing the oil filter half way through and toping the oil off at the same time."The restraining order says you're only allowed to touch me in freefall" =P Quote Share this post Link to post Share on other sites

Scoop 0 #28 June 4, 2007 We used to run the racing cars on Castrol R40. That stuff is so thick you have to wire in a 24volt external starter rig to turn it over. But once its up to temperature it has amazing protective qualities. Any old timers who were into high perfomance engines or racing cars will know the gorgeous distinctive smell of R40. The engine building company I worked for would only allow their engines to go out with R40 in them. Try and buy it though and you'll either get looked at blankly or laughed out the office until they realise you're being serious. Quote Share this post Link to post Share on other sites
Gawain 0 #29 June 4, 2007 QuoteIt's a 2000 civic si, with just at 110,000 miles. I shouldn't have to flush the engine should I. I should just be able to use the new oil next time I get an oil change, and yes the filter as well. That's correct. Don't worry about flushing.So I try and I scream and I beg and I sigh Just to prove I'm alive, and it's alright 'Cause tonight there's a way I'll make light of my treacherous life Make light!

jm951 0 #30 June 4, 2007 If you're already running synthetic, stay with it. If you've been running dino, and are thinking of switching, you might have problems with leaks where there weren't any before. Key is to change regularly and stick with what's recommended viscosity wise. AVOID Quaker State of any type. Every engine I've torn down that had been run with QS had major sludge buildup.
