Easy question but nothing is that simple. Which Oil is best for our 308s? 25K mile 1908 GTSI. Oh and do you recommend buying the fuel injection cleaner from the stores? STP? Lucas?
Is the 08 GTS for sale?? Yuk yuk! Try the search engine you will be more undecided after you learn about oil! Lost
As far as I'm concerned, Chevron Techron (concentrate) is the only additive for cleaning injectors proven to work; I use it every 90 days or so in all my cars; and have for years. The PO of my 308 used Lucas treatment andeven gave me a new bottle) but after two tanks with Techron, it ran considerably smoother especially under 3000 RPM. I also buy Chevron gas when I can. Recommending oil, on the other hand, is like recommending Scotch; lots of opinions but in reality most do the trick. Did '08s have a crank...for starting?
Actually, this is something that is really starting to burn me up with regard to H-D. I wish for the life of me I had run Castrol 20W-50 in my Softail but no of course I ran with H-D 20W-50. The bike has 130,000 miles and is air cooled plus with 22 years and all yes that's good. Now, though, they are charging $7 a quart for the same non-synthetic oil!!!
Ferrari issued a bulletin in the 90s stating their recommendation for all v8s, including all prior v8 engines, was 5w40. I run 0w40 in my 328.
My racing buddy says I should run Valvoline VV211 20-50 to slow down (even stop) the multiple leaks and also because it has more zinc for better protection of the solid lifters.
20-50 is too thick. Both with my 911's and with the last 4 3x8's I have had i switched to Redline 10-40. I had an 85 911 Targa, 58,000 1 owner miles on it. Had Bradd Penn 20-50 in it. Parked next to it was my other 911, a 87 Slopenose with the same 3.2 in it. 15,000 miles on rebuilt engine, 146,000 on the car. Use Redline 10-40 in it, and thats what was in it when I bought it. ( Previous shop had been servicing the car with Redline for years) You could walk into my garage, fire them both up side by side, and HEAR the difference. The 87 with the thinner Redline oil revved quicker, and had instant oil pressure. The Targa with 20-50 Bradd Penn took a few turns to "catch" and it took several seconds to have oil pressure. Both cars had great hot oil pressure, 2.5-3 bar fully warmed up. I am a firm believer in thinner oils. PS: My Slopenose does not leak, even though its been running on Redline oil for years. 20-50 is too damn thick for these old cars.
Is'nt the ZDDP discussion more applicable to air-cooled engines like Porsche 911/912/356? Does anybody know the zinc (ZDDP) content in the AGIP SINT 2000 oil? Thanks.
Increasing oil weight to stop leaks? If its too heavy to flow through leak, think of where it can't flow inside the engine. Sounds like something a "No credit? No problem" used car lot would do.
I add a can of BG MOA. Every car, every oil change. Even my truck i drive every day. Redline 10-40 probably already has enough zinc for the 3000 miles a year I drive.
The zinc thing is a non issue for these engines. The whole issue is about "flat tappet" motors. These motors aren't them. Forget about it. Do what Ferrari recommended in the 90's - use 5W40 (or current 0W40). Either way the viscosity is the same - 40. The lighter the W weight, the quicker the oil gets to where it needs to go when the engine is cold. The top end - 40 - is the same regardless of the W number. So 10W40, 5W40 and 0W40 are the same oil to your engine at normal operating temp. Note that if you're talking dino oil, it's a different deal. Use Syn.
